Hi When i do a 'losetup -a' while a manually setup encrypted loop is 'zero'ed with dd if=/dev/zero of=/dev/loop<x> bs=4096 count=<y> It blocks, just before the written to loop would be printed, until dd is finished, which may take several hours. As even after 'KILL'ing the process it stays in the process list, i assume that something on the kernel-site is blocking.

No, the Real Programmer wants a "you asked for it, you got it" text editor -- complicated, cryptic, powerful, unforgiving, dangerous. - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
