Previously 'expression->initrd' would return the directory that contains
the 'initrd' file; now it returns the complete file name for that file.
* gnu/system/linux-initrd.scm (expression->initrd)[builder]: Change
output file name to "initrd.cpio.gz". Tail-call 'file-append' to return
the complete file name.
* gnu/system.scm (operating-system-initrd-file): Remove 'file-append'
call.
* gnu/build/linux-initrd.scm (write-cpio-archive): Check whether OUTPUT
already has the ".gz" suffix; rename if before invoking GZIP if it does,
and otherwise after.
* gnu/system/vm.scm (expression->derivation-in-linux-vm)[builder]: Do
not append "/initrd" to #$initrd.
This is an incompatible change visible to users via the 'initrd' field
of 'operating-system'. However, assuming the user's 'initrd' value
tail-calls to 'raw-initrd' or 'base-initrd', the switch to non-monadic
style is invisible.
* gnu/system/linux-initrd.scm (expression->initrd): Use 'computed-file'
instead of 'gexp->derivation'.
(raw-initrd, base-initrd): Adjust docstring to mention non-monadic
return.
* gnu/system/vm.scm (expression->derivation-in-linux-vm): Adjust
accordingly.
* gnu/system.scm (operating-system-directory-base-entries)
(operating-system-initrd-file)
(operating-system-boot-parameters): Adjust accordingly.
* doc/guix.texi (operating-system Reference)
(Initial RAM Disk): Update.
* gnu/system.scm (bootable-kernel-arguments): Remove 'kernel-arguments'
parameter and return only the base list of kernel arguments. Rename
'system.drv' to 'system'.
(operating-system-kernel-arguments): Adjust accordingly and remove
'system.drv' parameter.
(read-boot-parameters-file): Adjust accordingly. Remove 'if params'
since dominating code assumed PARAMS is always true.
(operating-system-boot-parameters): Remove 'system.drv' parameter; add
#:system-kernel-arguments? instead and honor it.
(operating-system-bootcfg): Adjust accordingly.
(operating-system-boot-parameters-file): Likewise.
* gnu/system/vm.scm (system-qemu-image/shared-store-script): Remove
'os-drv' variable. Adjust call to 'operating-system-kernel-arguments'.
This significantly improves read throughput when running things like
"guix hash -r ...".
* gnu/system/vm.scm (%linux-vm-file-systems): Add 'flags' for "store".
Add "cache=loose" to every file system.
Fixes <https://bugs.gnu.org/32652>.
* gnu/system/vm.scm (operating-system-uuid)[service-name,
file-system-digest]: New procedures.
Map these over services and file systems and hash the result.
* tests/guix-system.sh: Add test.
* gnu/build/install.scm (register-closure): Add #:reset-timestamps? and
and #:schema; honor them. Rewrite in terms of 'register-path'.
(populate-single-profile-directory): Add #:schema and honor it. Make
/var/guix/profiles and /var/guix/gcroots.
* gnu/build/vm.scm (root-partition-initializer): Pass
#:reset-timestamps? to 'register-closure'.
* gnu/system/vm.scm (not-config?): New procedure.
(guile-sqlite3&co): New variable.
(expression->derivation-in-linux-vm)[config]: New variable.
[builder]: Use 'with-extensions'.
(iso9660-image)[schema, config]: New variables.
Wrap build expression in 'with-extensions'; add 'sql-schema' call.
Remove GUIX from INPUTS.
(qemu-image)[schema, config]: New variables.
Wrap body in 'with-extensions'.
(system-docker-image)[not-config?]: Remove.
[config]: Use 'make-config.scm'.
[schema]: New variable.
[build]: Use 'with-extensions'. Add call to 'sql-schema'. Remove GUIX
from INPUTS.
* gnu/system/file-systems.scm (%store-prefix): Check whether
'%store-prefix' is defined.
* guix/scripts/pack.scm (self-contained-tarball)[not-config?]
[libgcrypt, schema]: New variables.
[build]: Wrap in 'with-extensions'. Adjust imported module list to use
'make-config.scm' for (guix config).
* gnu/system/vm.scm (expression->derivation-in-linux-vm)
[user-builder]: Define in non-monadic style as 'program-file'.
[loader]: Likewise, and 'execl' USER-BUILDER instead of loading it.
(system-docker-image): Pass BUILD as the second
argument to 'expression->derivation-in-linux-vm'.
(make-iso9660-image, qemu-image): Remove call to 'reboot'.
The previous implementation of 'read-reference-graph' was good enough
for many use cases, but it discarded the graph structure, which is
useful information in some cases.
* guix/build/store-copy.scm (<store-info>): New record type.
(read-reference-graph): Rewrite to return a list of <store-info>.
(closure-size, populate-store): Adjust accordingly.
* gnu/services/base.scm (references-file): Adjust accordingly.
* gnu/system/vm.scm (system-docker-image): Likewise.
* guix/scripts/pack.scm (squashfs-image, docker-image): Likewise.
* tests/gexp.scm ("gexp->derivation #:references-graphs"): Likewise.
The 'title' field was easily overlooked and was an endless source of
confusion. Now, the value of the 'device' field is self-contained.
* gnu/system/file-systems.scm (<file-system>): Change constructor name
to '%file-system'.
[title]: Remove.
(<file-system-label>): New record type with printer.
(report-deprecation, device-expression)
(process-file-system-declaration, file-system): New macros.
(file-system-title): New procedure.
(file-system->spec, spec->file-system): Adjust to handle
<file-system-label>.
* gnu/system.scm (bootable-kernel-arguments): Add case for
'file-system-label?'.
(read-boot-parameters): Likewise.
(mapped-device-user): Avoid 'file-system-title'.
(fs->boot-device): Remove.
(operating-system-boot-parameters): Use 'file-system-device' instead of
'fs->boot-device'.
(device->sexp): Add case for 'file-system-label?'.
* gnu/bootloader/grub.scm (grub-root-search): Add case for
'file-system-label?'.
* gnu/system/examples/bare-bones.tmpl,
gnu/system/examples/beaglebone-black.tmpl,
gnu/system/examples/lightweight-desktop.tmpl,
gnu/system/examples/vm-image.tmpl: Remove uses of 'title'.
* gnu/system/vm.scm (virtualized-operating-system): Remove uses of
'file-system-title'.
* guix/scripts/system.scm (check-file-system-availability): Likewise,
and adjust fix-it hint.
(check-initrd-modules)[file-system-/dev]: Likewise.
* gnu/build/file-systems.scm (canonicalize-device-spec): Remove 'title'
parameter.
[canonical-title]: Remove.
Match on SPEC's type rather than on CANONICAL-TITLE.
(mount-file-system): Adjust caller.
* gnu/build/linux-boot.scm (boot-system): Interpret ROOT here.
* gnu/services/base.scm (file-system->fstab-entry): Remove use of
'file-system-title'.
* doc/guix.texi (File Systems): Remove documentation of the 'title'
field. Rewrite documentation of 'device' and document
'file-system-label'.
* gnu/system/vm.scm (system-docker-image): New procedure.
* guix/scripts/system.scm (system-derivation-for-action): Add a case for
docker-image, and in that case, call system-docker-image.
(show-help): Document docker-image.
(guix-system): Parse arguments for docker-image.
* doc/guix.texi (Invoking guix system): Document "guix system
docker-image".
* gnu/system/examples/docker-image.tmpl: New file.
* gnu/build/vm.scm (load-in-linux-vm): Make a shared temporary directory
available in the VM.
* gnu/system/vm.scm (%linux-vm-file-systems): Add a corresponding entry.
Fixes <https://bugs.gnu.org/30667>.
Reported by Björn Höfling <bjoern.hoefling@bjoernhoefling.de>.
* gnu/system/vm.scm (file-system->mount-tag): Use 'sha1' to compute the
tag.
Fixes a regression in installation tests, whereby 'guix system init'
would report that virtio modules are missing for the target devices.
In practice virtio modules were always available since 'base-initrd' was
always called with #:virtio? #t. This commit simply moves them to
'%base-initrd-modules' so that 'guix system' knows they're available.
Reported by Danny Milosavljevic <dannym@scratchpost.org> at
<https://debbugs.gnu.org/cgi/bugreport.cgi?bug=30629#112>.
* gnu/system/linux-initrd.scm (default-initrd-modules): Add virtio
modules.
(base-initrd): Remove #:virtio? and 'virtio-modules'.
* gnu/system/vm.scm (expression->derivation-in-linux-vm)
(system-qemu-image, virtualized-operating-system): Remove uses of
#:virtio?.
* doc/guix.texi (Initial RAM Disk): Update 'base-initrd' doc.
Fixes a regression introduced in
bc499b113a, whereby the default initrd
used by 'expression->derivation-in-linux-vm' would lack all the usual
modules: virtio, nls_iso8859-1, etc.
* gnu/system/vm.scm (expression->derivation-in-linux-vm): Pass
#:linux-modules to 'base-initrd'.
This avoids the hard-coded "/dev/sda1", which only made sense when the
image is run with "qemu-system-x86_64 -hda", not when it's passed to
Xen, etc.
Reported by Andreas Enge <andreas@enge.fr>.
* gnu/system/vm.scm (system-qemu-image): Define 'root-uuid', use it as
the 'device' field for "/", and pass it to 'qemu-image'.
This improves the performance of the shared store for operations involving
lots of files, e.g. searching through the store.
* gnu/system/vm.scm (mapping->file-system): Add cache=loose to options.
* gnu/bootloader/extlinux.scm (install-extlinux): Factorize bootloader
writing in a new procedure write-file-on-device defined in (gnu build
bootloader).
* gnu/build/bootloader.scm: New file.
* gnu/local.mk (GNU_SYSTEM_MODULES): Add new file.
* gnu/system/vm.scm (qemu-img): Adapt to import and use (gnu build bootloader)
module during derivation building.
* gnu/scripts/system.scm (bootloader-installer-derivation): Ditto.
* gnu/build/vm.scm (load-in-linux-vm): New argument #:target-arm32.
Use it to adapt command for qemu-system-arm. This implies to choose a
machine ("virt"), use the correct console port "ttyAMA0", disable KVM use
that is buggy on some ARM boards (Odroid XU4 for example) and use user mode
network stack instead of NIC. Gather all those options in a new variable
"arch-specific-flags".
* gnu/system/vm.scm (expression->derivation-in-linux-vm): Pass
to load-in-linux-vm "#:target-arm32?" argument.
* gnu/system/vm.scm (qemu-img): Do not add EFI partition if we are targetting
ARM.
UEFI support on u-boot is still experimental, so do not add EFI partition on
ARM for now.
* gnu/system/vm.scm (system-disk-image, system-qemu-image,
virtualized-operating-system): Replace base-initrd by
(operating-system-initrd os).
The system produced were always using base-initrd even if the user had
defined a custom initrd based on raw-initrd in the os declaration.
* gnu/system/vm.scm (operating-system-uuid): Use 2^32 - 1 instead of
2^32 as hash size.
On some 32 bit system (ARM for example), 2^32 exceeds hash max
size (ULONG_MAX = 2^32 - 1).
* gnu/system/vm.scm (qemu-image): When guessing the root-size, use a lower
bound of 20 MiB, otherwise the root file system size is sometimes 0 MiB in
size.
This makes collisions less likely than when using a label to look up the
partition. See <https://bugs.gnu.org/27735>.
* gnu/system/vm.scm (operating-system-uuid): New procedure.
(system-disk-image): Define 'root-uuid' and use it for the root file
system. Pass it to 'iso9660-image' and 'qemu-image'.
Conceptually a UUID is just a bytevector. However, there's software out
there such as GRUB that relies on the string representation of different
UUID types (e.g., the string representation of DCE UUIDs differs from
that of ISO-9660 UUIDs, even if they are actually bytevectors of the
same length). This new <uuid> record type allows us to preserve
information about the type of UUID so we can eventually convert it to a
string using the right representation.
* gnu/system/uuid.scm (<uuid>): New record type.
(bytevector->uuid): New procedure.
(uuid): Return calls to 'make-uuid'.
(uuid->string): Rewrite using 'match-lambda*' to accept a single 'uuid?'
argument.
* gnu/bootloader/grub.scm (grub-root-search): Check for 'uuid?' instead
of 'bytevector?'.
* gnu/system.scm (bootable-kernel-arguments): Check whether ROOT-DEVICE
is 'uuid?'.
(read-boot-parameters): Use 'bytevector->uuid' when the
store device is a bytevector.
(read-boot-parameters-file): Check for 'uuid?' instead of 'bytevector?'.
(device->sexp): New procedure.
(operating-system-boot-parameters-file): Use it for 'root-device' and
'store'.
(operating-system-bootcfg): Remove conditional in definition of
'root-device'.
* gnu/system/file-systems.scm (file-system->spec): Check for 'uuid?' on
DEVICE and take its bytevector.
* gnu/system/mapped-devices.scm (open-luks-device): Likewise.
* gnu/system/vm.scm (iso9660-image): Call 'uuid-bytevector' for the
#:volume-uuid argument.
* gnu/system/vm.scm (system-qemu-image/shared-store-script): Add
#:options parameter and honor it.
(<virtual-machine>): New record type.
(virtual-machine): New macro.
(port-forwardings->qemu-options, virtual-machine-compiler): New
procedures.
* gnu/system/vm.scm (expression->derivation-in-linux-vm): Add
#:single-file-output? and pass it to 'load-in-linux-vm'.
(iso9660-image): Pass #:single-file-output? to
'expression->derivation-in-linux-vm'.
* gnu/build/vm.scm (load-in-linux-vm): Add #:single-file-output? and
honor it.
