* gnu/system/vm.scm (<file-system-mapping>): New record type.
(%store-mapping): New variable.
(host-9p-file-system): Rename to...
(mapping->file-system): ... this. Replace 'source' and 'target'
parameters with 'mapping'. Set 'flags' field.
(virtualized-operating-system): Add 'mappings' parameter and honor
it.
(system-qemu-image/shared-store-script): Add 'mappings' parameter.
Pass it to 'virtualized-operating-system'. Use it in argument to
'common-qemu-options'.
* gnu/system/vm.scm (file-system->mount-tag, host-9p-file-system): New
procedures.
(virtualized-operating-system): Use 'host-9p-file-system' for the
store.
(common-qemu-options): Add 'shared-fs' parameter.
[virtfs-option]: New procedure.
Use it.
(system-qemu-image/shared-store-script): Adjust accordingly.
* gnu/system/vm.scm (system-qemu-image/shared-store-script): Add "$@" at
the end of the script.
(common-qemu-options): Remove trailing newline.
* doc/guix.texi (Invoking guix system): Document it.
* gnu/system/vm.scm (system-qemu-image/shared-store): Add
#:disk-image-size and #:full-boot? parameters and honor them. Pass
'#:copy-inputs? full-boot?', and change #:inputs argument.
* guix/scripts/system.scm (system-derivation-for-action): Pass
#:disk-image-size to 'system-qemu-image/shared-store'.
* doc/guix.texi (Invoking guix system): Mention use of '--image-size' in
conjunction with '--full-boot'.
This fixes regressions introduced in de1c158 ("system: Add support for
boot-time mapped devices.").
* doc/guix.texi (Initial RAM Disk): Adjust example with custom use of
'base-initrd'. Document #:mapped-devices parameter of 'base-initrd'.
* gnu/system/vm.scm (system-disk-image, system-qemu-image,
virtualized-operating-system): Adjust call to 'base-initrd' to new
signature.
* gnu/system/linux-initrd.scm (expression->initrd): Remove calls to
'imported-modules' and 'compiled-modules'. Use 'gexp->script' with
EXP. Add the result to TO-COPY. Make /init a symlink to that script,
and copy its closure into the "contents" directory. Add fake
/proc/self/exe symlink.
* gnu/build/linux-boot.scm (load-linux-module*): Add comment about mmap.
* gnu/system/vm.scm (system-qemu-image/shared-store-script): Add "-m
256". This turns out to be needed for initrds containing things like
e2fsck and several modules; with the default of 128 MiB, loading
libahci.ko may fail with -1.
* guix/gexp.scm (lower-reference-graphs): New procedure.
(gexp->derivation)[graphs-file-names]: New procedure.
Use 'lower-reference-graphs', and augment #:inputs argument as a
function of #:references-graphs.
* doc/guix.texi (G-Expressions): Adjust 'gexp->derivation' documentation
accordingly.

the #:references-graphs argument to
'expression->derivation-in-linux-vm'.
* gnu/system/file-systems.scm (<file-system>)[title]: New field.
* gnu/services/base.scm (file-system-service): Add #:title parameter.
In 'start' gexp, use 'canonicalize-device-spec' and honor TITLE.

operating-system-root-file-system, operating-system-initrd-file):
Adjust accordingly.
* gnu/system/linux-initrd.scm (file-system->spec): Likewise.
* gnu/system/vm.scm (system-disk-image): Add 'title' field for the root
file system.
* guix/build/linux-initrd.scm (mount-file-system): Expect the second
element of SPEC to be the title.
(boot-system)[root-mount-point?, root-fs-type]: Likewise.
* gnu/services/dmd.scm (dmd-configuration-file): Select
'canonicalize-device-spec'.
* gnu/system/vm.scm (system-disk-image)[root-label]: New variable.
Use it for the root file system, and pass it as #:file-system-label to
'qemu-image'.
* guix/build/vm.scm (format-partition): Add #:label parameter, and honor
it.
(initialize-hard-disk): Add #:file-system-label parameter, and pass it
to 'format-partition'.
* gnu/system/vm.scm (qemu-image): Add #:file-system-label parameter and
pass it to 'initialize-hard-disk'.
* guix/build/vm.scm (load-in-linux-vm): When MAKE-DISK-IMAGE?, use
'-drive ...,if=virtio' for better performance.
* gnu/system/vm.scm (qemu-image): Use /dev/vda instead of /dev/sda.
This fixes a circular dependency between (gnu system) and (gnu system
linux-initrd), where the latter could end up being compiled before
'file-system-type' was defined as a macro.
* gnu/system.scm (<file-system>, %fuse-control-file-system,
%binary-format-file-system): Move to...
* gnu/system/file-systems.scm: ... here. New file.
* build-aux/hydra/demo-os.scm, gnu/system/linux-initrd.scm,
gnu/system/vm.scm: Use it.
* gnu-system.am (GNU_SYSTEM_MODULES): Add it.
* gnu/system.scm (etc-directory): Change default value of #:profile.
Change contents of SHELLS. Use /run/current-system/profile/{s,}bin in
BASHRC.
(operating-system-boot-script)[%modules]: Add (guix build
linux-initrd). Add call to 'activate-current-system' in gexp.
(operating-system-initrd-file, operating-system-grub.cfg): New
procedures.
(operating-system-derivation): Don't build grub.cfg here and remove it
from the file union.
* gnu/system/vm.scm (qemu-image): Remove #:populate.
(operating-system-build-gid, operating-system-default-contents):
Remove.
(system-qemu-image): Remove call to
'operating-system-default-contents'. Use 'operating-system-grub.cfg'
to get grub.cfg. Add GRUB.CFG to #:inputs.
(system-qemu-image/shared-store): Likewise, but don't add GRUB.CFG to
#:inputs.
(system-qemu-image/shared-store-script): Pass --system kernel option.
* guix/build/activation.scm (%booted-system, %current-system): New
variables.
(boot-time-system, activate-current-system): New procedures.
* guix/build/install.scm (evaluate-populate-directive): Add case
for ('directory name uid gid mode).
(directives, populate-root-file-system): New procedures.
* guix/build/vm.scm (initialize-hard-disk): Replace calls to
'evaluate-populate-directive' by a call to
'populate-root-file-system'.
* gnu/services/dmd.scm (dmd-configuration-file): Use
/run/current-system/profile/bin.
* gnu/services/xorg.scm (slim-service): Likewise.
* gnu/system/vm.scm (qemu-image): Rename #:inputs-to-copy to #:inputs,
and #:initialize-store? to #:register-closures?. Add #:copy-inputs?.
Adjust build gexp accordingly.
(system-qemu-image): Remove #:initialize-store? argument and add
#:copy-inputs?.
(system-qemu-image/shared-store): Add #:inputs, #:register-closures?,
and #:copy-inputs? arguments.
* guix/build/vm.scm (register-closure): New procedure.
(MS_BIND): New variable.
(initialize-hard-disk): Rename #:initialize-store? to
#:register-closures?, #:closures-to-copy to #:closures, and add
#:copy-closures?.
Add 'target-directory' and 'target-store' variables.
Call 'populate-store' only when COPY-CLOSURES?.
Bind-mount the store to TARGET-STORE when REGISTER-CLOSURES? and not
COPY-CLOSURES?. Add call to 'register-closure'.
* gnu/system/vm.scm (virtualized-operating-system): Instead of
completely overriding 'file-systems', use 'remove' to filter out some
of those declared in OS.
(system-qemu-image): Likewise.
* gnu/system.scm (operating-system-derivation)[boot-file-systems]: Keep "/".
* gnu/system/linux-initrd.scm (file-system->spec): Keep the 'check?'
flag.
(qemu-initrd)[helper-packages]: New variable. Pass it as #:to-copy.
<gexp>: Add 'set-path-environment-variable' call. Remove #:unionfs
argument for 'boot-system'.
* gnu/system/vm.scm (%linux-vm-file-systems): Add 'check?' field/
(virtualized-operating-system): Likewise for the "9p" file system.
* guix/build/linux-initrd.scm (mount-root-file-system): Change #:unionfs
default. Call 'check-file-system' before mounting ROOT, when
VOLATILE-ROOT? is false.
(check-file-system): New procedure.
(mount-file-system): Honor 'check?' element in list; add
'check-file-system' call.
(boot-system): Remove #:root-fs-type and #:unionfs parameters.
[root-mount-point?, root-fs-type]: New variables.
Call 'mount-file-system' on all MOUNTS but "/".
Fixes a regression introduced in 83bcd0b.
* gnu/system/vm.scm (system-qemu-image): Override the 'file-systems'
field of OS. Add #:file-system-type parameter and honor it.
