An untethered or uncompressed diskless boot downloaded the root image
only from the deployment server and retried it forever when that server
failed. Try the other managers that answered discovery as well, as the
tethered urlmount already does.
urlmount limits each small range request to 10 seconds, but the single
whole-image download cannot take a total limit. Give up on a connect
after 10 seconds and on a transfer that stalls for 30 seconds instead,
so a hung server moves on to the next one.
The install runs before a policy is loaded, so the module index from
kernel-install and files of later post scripts stayed unlabeled and
systemd-modules-load failed. Relabel every local filesystem last.
With a tethered root (and on EL8 always), the initramfs writes the
overlay upper layer before the SELinux policy is loaded, so those files
are unlabeled_t. On a captured enforcing image sshd-keygen then cannot
search / and the node comes up without sshd.
Label exactly the upper layer paths with matchpathcon and chcon.
setfiles would recurse into the merged tree and restorecon is a no-op
before policy load. Built images have SELinux disabled and skip this.
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.
BUILDSRC is only set if imgutil build is run with --source, otherwise
the build host repos are used. If --source is not used, there is no
distribution symlink and add_local_repositores failed with 404.
Check if BUILDSRC is set and skip add_local_repositories if this is the
case.
Centralize the SELinux chcon helper and use it for downloaded
systemd units, onboot hooks, and apiclient files across EL7 through EL10.
Include chcon in captured EL initramfs images.
Without this fix the onboot services failed to start on SELinux enabled
captured image.
This allows the FS to just live, uncompressed, in cache.
This is generally a bad idea, however:
- In a hypothetically super-tuned diskless image, the lack of double-cache can offset the lack of compression
- The image will have supreme read performance
- It will have the most deterministic memory behavior

Retry umount during image2disk, if processes have the filesystem busy.

Invoke confignet properly during firstboot to set up additional interfaces.
Have sshd run during the install from '/sysroot', for convenience

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.
If the ip command shows altnames, do not
let the altnames interfere with locking
on to linktype.
Further, use show dev instead of grep to be more specific.
