This commit handles the relocation of ostree_repo prestaging data from
/opt/platform-backup to /opt/platform-backup/<release>. The miniboot.cfg
kickstart now looks for prestaged data in the release-specific location.
We also handle the backup partition name change across CentOS/Debian. In
the case of a downgrade the CentOS miniboot kickstart code is updated to
use the partition GUID rather than LABEL or PARTLABEL. The GUID is
constant across all releases and is therefore a more reliable indicator
of the backup partition.
Tech debt: Fix the arbitrary wait sleep calls used when configuring
VLAN addressing. Now uses the more efficient wait_for_interface
approach for the VLAN links.
Test Plan
PASS:
- Boot with prestaged data under /opt/platform-backup/<release>/
Ensure boot/install successfully uses prestaged data.
- Boot into older release under prestaged /opt/platform-backup/21.12
- Test moving from 22.12 -> 21.12 and 21.12 -> 22.12
- Ensure backup partition is found using GUID approach.
- Ensure boot/install successfully uses prestaged data.
- Boot into both current and older release with no prestaged data
- Test moving from 22.12 -> 21.12 and 21.12 -> 22.12
- Ensure boot/install is successful.
- Boot subcloud with bootstrap_vlan, ensure that the wait_for_interface
calls properly wait until the link is up.
