The /etc/crypttab line has

using cryptsetup lukesAddKey

Seems this is in bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=448665


Is this a bug or a feature?
Either way it is annoying.

As for the proposed fix, what if you don’t use crypttab?
And what if you don’t use /dev/urandom?
I have used a heavily modified rc.sysinit for the last several versions of Fedora calling a custom script to mount 5 LUKS partitions. mkinitrd in F9 now breaks everything.

My solution ( work around ) has been to turn swap off and un-mapp the swap partition just before I do a kernel install. This way mkinitrd does not see it. Upon reboot it gets mounted through my scripts and fstab ( in your case crypttab )

There is also an option during install to use a global LUKS passphrase.
Would that have been a solution for you ( Mike C. ) for your test box?
Anyone know how and where Fedora stores that passphrase for use? Is it a security issue?
