source_remote imageboot.sh is the last thing the diskless cmdline hook
runs, so returning early on a failed extraction ended the hook and left
dracut to time out. Falling through instead reaches the existing
/sysroot/sbin/init guard, which reports the failure and holds the node so
it stays reachable over ssh, as it did before extraction was checked.
Diskless profiles had the updatestatus callback in onboot.sh commented
out because no suitable status existed: 'complete' clears
deployment.pendingprofile, which the PXE responder requires to answer
the next network boot of a diskless node.
Add a 'booted' status that records the pending profile as
deployment.profile while leaving pendingprofile armed and skipping
autolock, and enable the onboot.sh callback in all diskless profiles.
nodedeploy now shows 'pending: <profile> (booted)' for a running
stateless node.
`unsquashfs` can use multiple CPU cores during image extraction, significantly reducing boot time.
For example the whole boot time from PXE to shell on a 8-core VM, from approximately 45 seconds to 20 seconds.
This PR adds `squashfs-tools` as a dependency. Since the package is smaller than 1 MB, the additional image size is justified by the performance improvement.
For backward compatibility, the existing `cp`-based extraction method is used when `unsquashfs` is unavailable, such as with images built before this change.
The extraction logic has also been moved into the common functions and is now shared between EL9, EL10, and Ubuntu.
Both untethered `squashfs` images and `confluent_multisquash` images are supported.
Images must be rebuilt to include `unsquashfs` and benefit from the faster extraction path.
Apply ruff's safe autofixes.
The changes are mechanical and behaviour-preserving. Issues fixed:
- F401: remove unused imports.
- F841: drop unused local variables and assignments, including discarded
await/return values, unused "except ... as e" bindings, and unused
"with ... as name" targets.
- F541: remove the f prefix from f-strings that contain no placeholders.
- E711: compare against None with "is"/"is not" instead of "=="/"!=".
- E712: test truthiness directly instead of comparing to True.
- E713: use "x not in y" instead of "not x in y".
- E714: use "is not" instead of "not ... is".
- E731: convert lambdas bound to a name into def statements.
- W291/W293: trim trailing whitespace on touched lines.
For one, ensure a unique machine-id. Broadly should be done, but critical for bonds to have unique mac
addressses in event of booting a captured image.
Fix ubuntu slow boot due to waiting forever for a network config. Have the transient network config bake into netplan for
a first pass before confignet comes along to do full configuration.
Clean up spurious error messages about grep true: and device busy on mounting overlay.
Reduce obvious output about skipped devices.
Rule out any read-only device.
Amend minimum size to 2GB.
Among same priority devices, select the smallest target.
A variant of the M.2 RAID enablement kit does not manifest with nvme
driver. Address this by allowing 'nvm' subsystype. to allow blank driver.
Also, to be on the safe side, have self.driver always be a string,
so it can be 'falsey' but still work as a string.
If syncfiles fails, keep it retrying.
Also, slow down sync checking to avoid hammering the system.
Further, randomized delay to spread highly synchronized requestors.
Block attempts to do multiple concurrent syncfile runs.
Some versions start manifesting nvme devnames with 'c', which
are to be used to interact with multipath to have raw devices
backing a traditional nvme device.
Needed the real losetup to handle read-only file.
busybox wc is way too slow, use ls instead.
Explicitly make /sysroot and load xfs, as that doesn't happen implicitly.
Accept a dangling symlink as viable init, since this is the case in Ubuntu.
Update hostname and ca certificates consistent with
ubuntu standards
