This commit introduces support for installing CentOS-based previous
release (21.12) in Debian.
There are two main components in this commit:
1. Handle the label change for the backup partition:
Platform Backup in 21.12 vs 'platform_backup' in Debian
This is accomplished by ignoring the label/partlabel entirely when
searching for an existing backup partition. Instead, the partition
GUID is used to locate the partition. The GUID does not change
between distributions.
2. Use pre-bundled CentOS kickstarts for subcloud installs in Debian
Since modifications are required to the CentOS kickstart files for the
above, we copy the relevant pre-bundled centos kickstarts (for miniboot
and prestaged ISO only) into a centos-specific directory under the
Debian /var/www/pages/feed/rel-${platform_release}/kickstart directory
structure, in order to be available for the gen-bootloader-iso-centos.sh
utility. These files are included in the platform-kickstarts .deb
package.
NOTES on how the pre-bundled files are created:
- We cannot use the files under bsp-file/kickstarts/*.cfg, since they
are not valid for 21.12 release (e.g. they refer to /var/www)
- Instead, files were taken from a valid 21.12 release and manually
merged with the pre-bundled files generated from this repo
GOING FORWARD:
Only the bundled files at kickstart/files/centos/*.cfg will be
maintained. At a later time, we may choose to remove the partial
kickstarts under bsp-files/kickstarts/*.cfg, since they are not used
anywhere.
Test Plan
PASS:
- Build full ISO, verify that the
/var/www/pages/feed/rel-23.09/kickstart/centos directory is populated
with the pre-bundled kickstart files
- Verify previous-release CentOS subcloud install/deployment under
Debian (requires patched 22.12 load)
- Verify current-release subcloud install under Debian
