Two things:


1. You might want to review the 'luksopen' script at the dm-crypt wiki:

http://www.saout.de/tikiwiki/tiki-index.php?page=luksopen&comzone=show#comments


and this entry by John Maher, which is specific to FC5:

http://www.saout.de/tikiwiki/tiki-index.php?page=EncryptHomeDirUsingLUKS



2. Modify the entry in /etc/fstab to

   /dev/mapper/sda5        /home       ext3   noauto     0 0


Changing the '1 2' to '0 0' will disable the boot time checking.


There is also a dedicated dm-crypt/LUKS e-mail list. More info at:
