Ubuntu 17.04 uses swapfiles by default.
If you select the "encrypt home folder" option when creating the main
user during Ubuntu 17.04 beta1 installation (which makes Ubiquity run
also the ecryptfs-setup-swap command), after installation the system
hangs a lot during boot, because it fails to activate swap (output of
"systemctl status swapfile.swap" says "failed to activate swap
/swapfile").
If you install Ubuntu 17.04 beta1 without selecting "encrypt home
folder", and only after installation you run the ecryptfs-migrate-home
utility, everything works. But as soon as you try to manually setup
encrypyted swap (by running ecryptfs-setup-swap), you get the same
problem as above.
This is due to an ecryptfs-utils bug.
In particular, ecryptfs-setup-swap puts in /etc/crypttab a line like this:
cryptswap1 UID=XXXXXXXX /dev/urandom swap,offset=1024,cipher=aes-xts-
plain64
(like there were a swap partition with UID=XXXXXXXX) while with a
swapfile it should put the following line:
cryptswap1 /swapfile /dev/urandom swap,offset=1024,cipher=aes-xts-
plain64
If you manually change that line and reboot, you get rid of the problem -
before rebooting, check also that your /etc/fstab file ends with:
#/swapfile none swap sw 0 0
/dev/mapper/cryptswap1 none swap sw 0 0
This bug indirectly affects also Ubiquity, since choosing the "encrypt
home folder" makes system hang a lot at boot (and when it finally starts
it has no swap).
I tried both with Ubuntu Budgie and with Ubuntu Gnome, the problem is
the same.
