Suspended Animation

I read somewhere that you can specify the resume device that uswsusp uses by UUID. I edited my config as follows:

josh@penryn64:~$ cat /etc/uswsusp.conf
# /etc/uswsusp.conf(8) -- Configuration file for s2disk/s2both
resume device = /dev/disk/by-uuid/ba2d5cd5-fd65-46c6-9be1-70851d8038f2
splash = y
compress = y
early writeout = y
image size = 1427192791
RSA key file = /etc/uswsusp.key
shutdown method = platform

It seems to work. There are no errors in /var/log/pm-suspend.log.
