Reported by Björn Höfling <bjoern.hoefling@bjoernhoefling.de>.
* gnu/system/vm.scm (file-system->mount-tag): Use 'sha1' to compute the
tag.
Previously the KNOWN-FS value used in 'essential-services' would be
incomplete: it would lack all the file systems provided by services that
extend 'file-system-service-type' (/sys/fs/cgroup,
/proc/sys/fs/binfmt_misc, etc.) Consequently, upon shutdown,
'user-processes' would unmount these file systems before their
corresponding service had been stopped; when their corresponding (e.g.,
'file-system-/proc/sys/fs/binfmt_misc') was stopped, its 'umount' call
would fail.
This was harmless in practice, but this patch makes sure things work as
intended and file systems are unmounted in the right order.

* gnu/system/install.scm (cow-store-service-type): Adjust comment.
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.

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.
I dediced to keep adding /tmp as tmpfs since I was not able to trigger bug
while still using unionfs, so I could not verify whether this mount is still

* gnu/system/install.scm (make-cow-store): Mount /gnu/store without additional

since now using the mount syscall. [unionfs]: Remove now unused function.
(%installation-services): Update comment.
(installation-os)[file-systems]: Update comment.
Overlayfs is part of the kernel, while unionfs needs FUSE. This also reduces
the size of the initrd by ca. 4.3% (487K).
* gnu/build/linux-boot.scm (mount-root-file-system): Remove optional parameter

* gnu/system/vm.scm (operating-system-uuid): Use 2^32 - 1 instead of

By referencing guile from the initrd output explicitly, it will be present in
the store when this initrd is used. If the exact guile used within the initrd
isn't present in the store, then after root is switched during the boot

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.
