BTRFS and Qubes OS

@marmarek Sorry if this is wrong place for asking, but I wanted to have insights on where the ecosystem is moving.

  • TLVM adds lots of overhead, complexity and performance penalties
  • BRTFS is offered as second installation candidate under QubesOS installer, where XFS is not offered
  • TLVM is still default installation method
  • 4k templates are coming along, proving BRTFS to be resilent here, and where TLVM would probably benefit and loose some drawback performance points when compared to BRTFS.

The Reason I ask is that other OSes switched to BRTFS and I’m wondering if Heads should also take steps into having brtfsprogs built and included. wyng-backups now supports xfs/brtfs as well. But as you know, Heads cannot pack everything for all use cases so question here is:

Is QubeSOS default partitioning scheme expected to change to BRTFS by default on Q4.2 release or is TLVM still expected to stay the default instlalation method?

cross-linking to issue showing newer OS installers and Heads documentation and filesystem support might need to be reconsidered:
