Hi,
Thanks for the quick reply. I wasn't aware of the changes in
crypttab syntax with systemd; but changing it the way you described it
did the trick for swap.
You're right, on digging deeper (logs) I found that the fsck had
failed earlier as well but I never noticed it as the boot process
wasn't interrupted. I didn't face it again after setting passno. to 0.
I had heard about btrfs being released without a proper fsck in place
but I thought that was long ago and that btrfsck was ready for general
use.
Rodrigo: I already solved it, but thanks for your reply anyway.
