No OverlayFS support since Linux 6.8 #308

Hello,

I'm the developer of the Kaisen Linux GNU/Linux distribution.

I use Timeshift with the grub-btrfs software, and I was developed an initramfs script to mount the / partition in the OverlayFS when the kaisen-grub-btrfs cmdline is used (I created a patch on my grub-btrfs package to add this cmdline when the GRUB entry is created). The initramfs script.

Since the Linux 6.8 release, Timeshift detects that the / partition is mounted in read-only, but the / partition is mounted on read-write (the lower, upper and workdir are differents directories).

I tried to add mountoptions, but not works.

How to fix this problem? An exclusion can be added on the Timeshift code base to exclude the OverlayFS?

Thank you.

Kind regards,

Kevin CHEVREUIL
