Hi, I've a problem with the losetup when it is patched with loop-aes. If I'm using the unpatched losetup (from util-linux-ng) and looping a device like /dev/disk/by-id/ata-WDC_WD6400AAKS-22A7B2_WD-WCASY7780706-part3 it is using readlink to track down the link to e.g. /dev/sda3. But if I'm using the patched losetup I don't see any readlink in the strace. Because no readlink is used there is a problem with device names which have more then 64 characters (the field "lo_name" is an array of 64 char). It is truncated like /dev/loop0: [0010]:6229 (/dev/disk/by-id/ata-INTEL_SSDSA2M160G2GC_CVPO939201JX160AGN-par) encryption=AES128 That does make trouble with e.g. btrfs, because mkfs.btrfs uses the devicename provided by losetup to check if a device is mounted. That can't work with an incomplete devicename. Any thought on this problem? Regards, Felix
