Description Matt McCutchen 2008-02-24 01:46:10 UTC 
Description of problem:
I use a swap partition encrypted with dm-crypt and LUKS.  It is listed in
/etc/fstab as "/dev/mapper/swap".  mkinitrd fails to include the necessary
cryptography modules in the initrd to resume from hibernation using the swap
partition.  This is because function "findstoragedriver" does not check for a
"/dev/mapper"-format name.

Version-Release number of selected component (if applicable):
mkinitrd-6.0.30-1.fc9

How reproducible:
Always

Steps to Reproduce:
1. Make an LUKS-encrypted partition.
2. Add the partition to crypttab with name "swap".
3. Add the following to /etc/fstab:
/dev/mapper/swap	swap	swap	defaults	0 0
4. Install a new kernel with yum.

Actual results:
The necessary cryptographic modules are not included in the new initrd.

Expected results:
The modules are included.

Additional info:
The patched mkinitrd from bug 124789 comment 118 recognizes the partition fine.
 A workaround for the current mkinitrd is to list the partition in /etc/fstab
using a /dev/dm-X name, but the number is more fragile if dm partitions are
reconfigured in the future.
