generator: Fix soft-reboot for var, sysroot, and boot
A bare `systemctl soft-reboot` on ostree/bootc systems was broken in
several ways because the generator and prepare-root were not accounting
for the fact that soft-reboot does not re-run the initramfs.
The var.mount unit had DefaultDependencies=yes, which pulled in implicit
After= dependencies on device units. After soft-reboot, these device
units get stuck in 'tentative' state while udev restarts, causing
var.mount to stall indefinitely. Fix this by setting
DefaultDependencies=no with explicit ordering After=local-fs-pre.target
sysroot.mount.
For /sysroot, systemd auto-generates the mount unit from mountinfo with
Conflicts=umount.target, causing it to be unmounted during soft-reboot
shutdown. Generate a drop-in with DefaultDependencies=no to prevent this.
We use a drop-in because the generator does not know the What= device
parameter — systemd gets that from mountinfo.
For /boot on same-partition setups, move the bind-mount from
ostree-prepare-root into the generator as a full boot.mount unit with
DefaultDependencies=no. This handles normal boot, bare soft-reboot, and
staged deployment soft-reboot uniformly. The static (non-systemd) path
in ostree-prepare-root-static.c retains its own bind-mount since the
generator does not run there.

bootconfig: Preserve extension BLS keys across staged deployments
When a deployment is staged via ostree_sysroot_stage_tree_with_options(),
the deployment metadata is serialized to /run/ostree/staged-deployment
as a GVariant. During finalization at shutdown,
_ostree_sysroot_reload_staged() creates a fresh OstreeBootconfigParser
and only restores the "options" key from the serialized kargs. Any
additional BLS keys that were set on the bootconfig are silently dropped.
The parse/write/clone paths in OstreeBootconfigParser already handle
unknown keys generically (the "Write unknown fields" loop in
write_at()), so keys survive direct deployments and in-memory
operations. The gap is exclusively in the staged deployment roundtrip,
where a fresh bootconfig is rebuilt from just the kargs strv.
This matters for the upcoming bootc `loader-entries set-options-for-source`
feature, which stores kernel argument ownership as extension BLS keys
(e.g. `x-options-source-tuned nohz=full isolcpus=1-3`). On bootc
systems with transient /etc, tools like TuneD lose track of which kargs
they own because their state files are wiped on reboot. Tracking
ownership directly in the BLS config on /boot solves this, but only if
the keys survive staging. systemd-boot, GRUB, and zipl all ignore
unknown BLS keys, so extension keys are safe.
Fix this by following the same pattern used for overlay-initrds:
1. Add _ostree_bootconfig_parser_get_extra_keys_variant() which returns
all non-standard BLS keys as an a{ss} GVariant. Standard keys
(title, version, options, linux, initrd, devicetree) are excluded
since they are rebuilt from scratch during finalization. All other
keys are preserved, trusting the caller.
2. In ostree_sysroot_stage_tree_with_options(), serialize any extra
keys as "bootconfig-extra" in the staged GVariant dict. Since
_ostree_deployment_set_bootconfig_from_kargs() creates a fresh
bootconfig with only the "options" key, the code falls back to
the merge deployment's bootconfig for extra keys. This ensures
keys are inherited across staged deployments without the caller
needing to re-set them.
3. In _ostree_sysroot_reload_staged(), restore extra keys from the
"bootconfig-extra" dict onto the deployment's bootconfig via
ostree_bootconfig_parser_set().
The function is private (_ostree_ prefix) since only ostree's own
staging code uses it. No new public API, no changes to .sym files,
no changes to GIR or Rust bindings.
Backwards compatibility:
- Old ostree ignores the unknown "bootconfig-extra" key in the a{sv}
dict (extension keys silently lost, same as before this patch).
- New ostree gracefully handles the absence of "bootconfig-extra" in
staged data written by older versions (g_variant_dict_lookup returns
FALSE, no restoration attempted).

libarchive: Handle UTF-8 filenames without locale dependency
When importing archives (including OCI container layers), libarchive
attempts to convert filenames from UTF-8 to the current locale charset.
In POSIX/C locale (which uses ASCII), this conversion fails for any

This is triggered by Python 3.14 which creates a "𝜋thon" symlink in
venvs, and affects bootc installations in environments where LANG is
not set (defaulting to POSIX locale).
Fix this by:
1. Using archive_entry_pathname_utf8() and archive_entry_symlink_utf8()

2. Falling back to the regular accessors with explicit UTF-8 validation
when the _utf8 variants return NULL
3. Accepting ARCHIVE_WARN from archive_read_next_header() since we now
validate UTF-8 ourselves rather than relying on libarchive charset
conversion
This matches the behavior of GNU tar which treats filenames as opaque

state-overlay: Fix ENODATA handling for GLib < 2.74
The state overlay feature fails on first boot with:
error: lgetxattr(user.ostree.deploymentcsum): No data available
This happens because `lgetxattrat_allow_noent()` checks for
`G_IO_ERROR_INVALID_DATA` to detect when an xattr doesn't exist.
However, GLib's `g_io_error_from_errno()` only maps `ENODATA` to
`G_IO_ERROR_INVALID_DATA` since GLib 2.74. Older versions (such as
GLib 2.68 shipped in CentOS Stream 9) return `G_IO_ERROR_FAILED`
instead, causing the check to fail and the error to propagate.
This creates a chicken-and-egg problem: the code tries to read the
`user.ostree.deploymentcsum` xattr before it can set it, but the read
fails on fresh overlay directories where the xattr hasn't been set yet.
Fix this by checking `errno == ENODATA` directly after the failed call,
which is portable across all GLib versions. Also rename the function
from `lgetxattrat_allow_noent` to `lgetxattrat_allow_nodata` to more
accurately reflect its purpose (ENODATA vs ENOENT).
This bug has existed since the state overlay feature was introduced in
v2024.1 but was masked on systems with GLib >= 2.74 (e.g., Fedora,
CentOS Stream 10) where the mapping happens to exist.

ostree-sign.ed25519/spki: Fix double free in set_sk()
When the gvariant is G_VARIANT_TYPE_BYTESTRING we need to duplicate
the data we get from g_variant_get_fixed_array(), otherwise we will
double-free it when we later free sign->secret_key.
Support using composefs signatures also with bootc commits
When using bootc, if you convert a signed ostree commit into an OCI
image `rpm-ostree compose container-encapsulate` you end up with a new
commit that isn't signed. However, the base commit object, and its
commitmeta are still in the image and will end up the repo, and
since https://github.com/bootc-dev/bootc/pull/1600 the base commit
id is available as the parent commit.
So, we change ostree-prepare-root to fall back to using the base
commit+commitmeta to find the expected composefs digest if the main
commit is not signed.
Note: This will only work with ostree-only commits. If you have any
layered data, then the content will change, and the composefs digest
in the base commit will not match the deployed one. This is expected
with such sealed commits though. If you want to layer, either disable
sealing, or create a new sealed ostree commit for the new image.
prepare-root: add allow_noent argument to load_variant
This is a minor preparation for a later change. Instead of
hand-rolling the G_FILE_ERROR_NOENT error check we add
a new allow_noent option.
Additionally, we move the handling of a no commitmeta being
an error to the caller of load_commit_for_deploy(), because
this check will be slightly more complex in the future.
Revert "Add ostree-shutdown.service: hide /sysroot and make /etc read-only"

umount sysroot.mount during soft-reboot.
Create a temporary bind-mount, use it to prepare /run/nextboot
and MNT_DETACH it when we are done.
Moving the physical root at /sysroot, we end up
with a mount cycle between / and /sysroot, forcing us to use
MS_DETACH during shutdown (d0c454c23637dceda6d7395dd2141b564e3efa47).

Add ostree-shutdown.service: hide /sysroot and make /etc read-only

So far during shutdown we've let systemd just try to sort things out

and so on.
systemd has some special casing for `-.mount` (i.e. `/`) and `etc.mount`

However it doesn't special case `/sysroot` - which is currently
an ostree-specific invention (when used in the real root).
We cannot actually unmount `/sysroot` while it's in use, and it
is because `/etc` is a bind mount into it. And we can't tear
down `/etc` because it's just expected that e.g. pid 1 and other
things hold open references to it - until things finally
transition into systemd-shutdown.
What we can do though is explicitly detach it during the shutdown
phase; this ensures that systemd won't try to clean it up then,
suppressing errors about its inability to do so.
While we're here, let's also remount `/etc` read-only; while
systemd itself will try to do so during systemd-shutdown.

else to be fixed.

But going farther here, there already is logic to use syncfs
for the repo when downloading objects (in a common case
we actually syncfs twice).
Since these are really the same operation, unify them:
- Add journaling to the repo one syncfs case
- Change the sysroot case to just call it
- Since we log consistently to the journal for all syncfs/fsfreeze
operations now, drop the SyncStats bits which was a way
to add info about that to a later journal message
