Many thanks for your help Shiv!
I've applied the patch to vol_id and un_vol_id in /lib/cryptsetup/checks/. Now, the automated creation of the swap device works again. Looking at the scripts, your explanation seems absolutely plausible to me. I've even cross-checked the detection by trying the following once with dev="/dev/null" and dev="/dev/sda1": > vol_id=`/lib/udev/vol_id -t $dev 2>&1` > pattern=`echo $dev | sed 's/\//\\\\\//g'` > unknown=`/lib/udev/vol_id -t /dev/null 2>&1 | sed "s/\/dev\/null/$pattern/g"` > if [ "$vol_id" != "$unknown" ] && [ "$vol_id" != "minix" ] && [ -z "$fs" ]; > then echo FILESYSTEM DETECTED; fi Seems to work... -- Encrypted SWAP partition not created/mounted https://bugs.launchpad.net/bugs/316607 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
