Maybe also Ubiquity needs to be patched, I am not sure since I did not have time to test it yet.
I did the following test to isolate the problems. 1) Fresh ubuntu 17.04 installation with no encrypted home (and no encrypted swap). /etc/crypttab is empty, and in /etc/fstab I have the following line: /swapfile none swap sw 0 0 2) After successfully running ecryptfs-migrate-home, I run ecryptfs-setup-swap (the "original" version, not the one with the above patch) and I get: INFO: Setting up swap: [/swapfile] device node not found WARNING: Commented out your unencrypted swap from /etc/fstab swapon: cannot open /dev/mapper/cryptswap1: No such file or directory Now in /etc/fstab I have: #/swapfile none swap sw 0 0 /dev/mapper/cryptswap1 none swap sw 0 0 and in /etc/crypttab I have: cryptswap1 UUID=98a3bb25-2c4d-4897-974c-d5dfcc16be8f /dev/urandom swap,offset=1024,cipher=aes-xts-plain64 If I run free, I see that I have no swap: total used free shared buff/cache available Mem: 8084440 1421116 4575096 273228 2088228 6086972 Swap: 0 0 0 3) I reboot, and the system hangs a lot during boot. I see "a start job is running for dev-mapper-cryptswap1.device". After a couple of minutes, the boot process ends and I can login. If I run "systemctl status swapfile.swap" and "free" I see that (unencryted) swapfile has been activated anyway. THIS IS DIFFERENT FROM WHAT I GOT WHEN DOING A FRESH UBUNTU 17.04 INSTALL WITH THE "ENCRYPT HOME FOLDER" OPTION SELECTED. In that case, I got the system hanging during boot, too, but when I finally managed to login I got no swap at all ("systemctl status swapfile.swap" returned "failed to activate swap /swapfile"). Looking at ubiquity scripts, I see that if encrypted home option is selected, it runs also ecryptfs-setup-swap (so ubiquity is actually affected by the bug described above); but the fact that system fails also to activate unencrypted swap seems to suggest that Ubiquity may need to be patched too. 4) ** Description changed: Description: Ubuntu Zesty Zapus (development branch) Release: 17.04 ecryptfs-utils: Installato: 111-0ubuntu4 Candidato: 111-0ubuntu4 Tabella versione: *** 111-0ubuntu4 500 500 http://it.archive.ubuntu.com/ubuntu zesty/main amd64 Packages 100 /var/lib/dpkg/status 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. + In particular, you get the following error when running ecryptfs-setup- + swap: + + INFO: Setting up swap: [/swapfile] + device node not found + WARNING: Commented out your unencrypted swap from /etc/fstab + swapon: cannot open /dev/mapper/cryptswap1: No such file or directory + 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). + This bug indirectly affects also Ubiquity, because when you choose the + "encrypt home folder" option during installation, ubiquity runs also + ecryptfs-setup-swap; since Ubuntu 17.04 uses swapfiles by default, and + ecryptfs-setup-swap does not work with swapfiles, after installation you + get the system hanging a lot at boot (and when it finally starts it has + no swap).
