I just tried to move
/usr to a small ssd I recently purchased. The ssd is formatted with LUKS and btrfs. Apparently systemd fails to start the cryptography target before the partitions are first mounted:
Nov 28 16:12:33 laptop systemd: Failed to start Remount Root and Kernel File Systems. Nov 28 16:12:33 laptop systemd: Unit systemd-remount-fs.service entered failed state. Nov 28 16:12:33 laptop systemd: systemd-remount-fs.service failed. Nov 28 16:12:31 laptop systemd-remount-fs: /bin/mount for /usr exited with exit status 1. Nov 28 16:12:33 laptop systemd-remount-fs: mount: UUID=... kann nicht gefunden werden
(The last part translates to uuid=xyz can not be found)
Nov 28 16:12:35 laptop systemd: Starting Cryptography Setup for usr-crypt... Nov 28 16:12:36 laptop systemd-cryptsetup: Set cipher aes, mode xts-plain64, key size 256 bits for device /dev/disk/by-uuid/...
Any idea on how to solve this?
