Fix Ubuntu 22 xfs and partuuid errors. #1892

Closed vimish closed 4 months ago

vimish commented 4 months ago

This PR fixes below issues:

  1. OS encryption failure on Ubuntu 22 For some reason, blkid or lsblk is not returning root partition's PARTUUID at the time we request it. The cause is still unclear. Updated the logic to not rely on the command ans use partuuid symlinks to get root partition's PARTUUID.

  2. XFS module corruption after OS disk encryption on Ubuntu 22 conv=sparse and bs=64K seems to be skipping some required blocks encryption causing the module corruption. Update bs to 16M so that blocks are not skipped.
