* guix/self.scm (*system-modules*): Restore previous behaviour and add all
installer files to #:extra-files field of the scheme-node.
* po/guix/POTFILES.in: Adapt it.
Source /etc/environment just before starting the installer. The login program
is supposed to load the environment variables of this file through PAM, but as

useful for the LANG environment variable.
* gnu/installer/build-installer.scm (installer-program-launcher): New exported

Previously 'expression->initrd' would return the directory that contains

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.

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.

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.

I dediced to keep adding /tmp as tmpfs since I was not able to trigger bug

(%installation-services): Update comment.

Overlayfs is part of the kernel, while unionfs needs FUSE. This also reduces

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
process, loading modules (such as (ice-9 popen)) won't work.
This fixes guix-patches bug #28399, "Fix mysql activation, and add a basic
test".
* gnu/system/linux-initrd.scm (expression->initrd)[builder]: Write out a file
called references in to the initrd output, which includes the store path for
guile.
* gnu/system/uuid.scm (uuid=?): New procedure.
* tests/uuid.scm ("uuid=?"): New test.
* gnu/build/file-systems.scm (partition-uuid-predicate)
(luks-partition-uuid-predicate): Use it instead of 'bytevector=?'.
* 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.
* gnu/system/uuid.scm (%fat32-uuid-rx): New variable.
(string->fat32-uuid): New procedure.
(%uuid-parsers): Add it.
* tests/uuid.scm ("uuid, FAT32, format preserved"): New test.
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.
