Goal:

• Implement several improvements to the BIB's partitioning logic:
  • It's possible to have custom mountpoints.
    • The goal is to be pretty flexible, but it should not be possible to nonsense mountpoints like /sys and /proc (the current ruleset in composer is fairly good).
    • The absolute minimal set is: /var/tmp, /local, /local/afs.cache, /var/log (requirements from a major customer).
  • It's possible to create LVM-based images. This means that all partitions are on LVs except /boot and /boot/efi.
  • If raw partitioning is used, there's no /boot by default. (This is aligned with https://issues.redhat.com/browse/RHELBU-2820 )
  • It's possible to create an LV-based swap.
  • It's possible to give VGs and LVs custom names.
  • It's possible to set custom mount options for fstab.

Acceptance Criteria:

• All goals are implemented.
• This is demoed.

Out of scope:

• No multiple VGs nor PVs on one image.
• Swapfiles (should be reasonable simple to define them in the bootable container).

Open question:

• Raw swap partitions
  • If it's too much effort to implement them right now, let's split them out into a separate epic/feature.
