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.
`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.
Fix SC2045 (error): Iterating over ls output is fragile. Use globs.
Add exception SC2068 exception for confluent_client/confluent_env.sh as this is intended.
SC2068 (error): Double quote array expansions to avoid re-splitting elements.
Allow arbitrary per-connection network settings, such as static routes
or a firewalld zone, to be specified as semicolon-delimited key=value
pairs on a net.*.extra_settings attribute. The keys are passed through
to the network backend of the deployed OS in its native syntax: nmcli
properties on NetworkManager systems, netplan YAML paths on netplan
systems, and ifcfg variables on wicked systems.
While curl and agama download are happy with the CA bundle, zypper was not. Have pre.sh properly set up the CA certs.
Additionally, indicate the install subdirectory of the repository to agama via it's cmdline conf.
Match autocons
Skip unless EFI x86_64.
If SPCR, trust it and use that unconditionally.
Otherwise, if only one can respond to TIOCMGET, then use that one.
If multiple can respond, but exactly one shows carrier, use that.
Agama ignores the dracut cmdline.d and uses only /proc/cmdline
Good news is they have their own agama.conf and they append to it rather than rewrite it.
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.
