Can't install use bcachefs as the root filesystem

soldier4messiah · June 3, 2026, 2:42pm

When I try to install cachyos using calamares, I try to format the root partition as bcachefs. As it is installing, it gives an error that pacstrap won’t work. Basically, it won’t actually install. I am using the most recent version of cachyos iso - 260426. I would like to use bcachefs in the root and I can’t do that. Please help. Thank you.
