I have no idea. But, if I disable the swap partition the system boots just fine. If I enable it, fsck tries to run and the partition is complains about is the swap partition. I have no idea why systemd.fsck does this. :-/ [snip] > I have the same setup on Debian Sid with systemd, just like you: > > ,----[ /etc/crypttab > | # <target name> <source device> <key file> <options> > | cswap /dev/disk/by-id/md-uuid-a805edd5:bcfd4c98:ce747c2c:77d42131 > /dev/urandom swap,cipher=aes-cbc-essiv:sha256,size=256 > `---- Thank you!! I think I just found out what my note "systemd.fsck doesn't like UUID's" meant! I was assuming it was in the /etc/fstab or somewhere, but when I noticed you have the /dev location of your disk and I have a UUID in the /etc/crypttab I decided to give it a try. $ grep swap /etc/crypttab # causes systemd to fsck swap #sda3_crypt UUID=ef2496cd-ca4d-43aa-8c90-dba084029f6e /dev/urandom cipher=aes-xts-plain64,size=256,swap # systemd doesn't fsck swap sda3_crypt /dev/sda3 /dev/urandom cipher=aes-xts-plain64,size=256,swap I reverted all of my changes that I took notes on and bada-bing-bada-boom! It works now! Out of curiosity (and because I have a sacrificial VM with various snapshots I can easily reset to), I setup a encrypted swap on a Ubuntu 15.04 alpha (pre-systemd) with my previous method. Swap worked perfectly. I 'apt-get update'd 15.04 and installed the systemd package (and a lot of "dependencies" o_O). On the first boot systemd.fsck had issues with swap and didn't mount it. I changed it to the disk instead of UUID and rebooted. Works!! So it isn't just systemd in Debian either. At least I now know in the future not to use UUID for swap in /etc/crypttab! Sometimes it seems that the most painful and frustrating problems have the most trivial solutions. :-D Thanks! ~Stack~
