cryptdisks runlevel configuration for lvm2 + encrypted swap file

[Jimmy Wu <jimmywu013@gmail.com>]

Dear List,

I have an encrypted swap file located inside /var, which is on a 
separate LVM2 logical volume from /, but it does not get mounted on 
boot.  Everything I've been able to find either implies my setup should 
work or is geared toward swap partitions, not swap files.  I even put 
aside my reservations about messing with the links in rc.d, (tried 
starting cryptdisks in runlevels 2-5 and other things as well) but since 
it didn't work so I restored everything back to the default before I 
broke anything, and came here to ask for help/advice instead.

I've copied the following relevant info below:
/etc/crypttab contents
relevant /etc/fstab entries
relevant rc?.d symlinks

My system is Squeeze 2.6.32-5-amd64 
Running invoke-rc.d cryptdisks start && swapon -a after boot works.
During the boot process I can see messages on the console that show
"Starting early crypto disks" succeeds, but "Starting remaining crypto 
disks" failed.

I'd appreciate any pointers as to what I am doing wrong or how I can 
better troubleshoot the problem.

Thanks,

Jimmy
