[dm-crypt] found more than one resume device candidate

[scar]

I have cryptsetup 1.6.1 installed on Ubuntu 14.04, i went and installed 
the uswsusp package for hibernation, and i am getting the warning below 
when update-initramfs is running:

cryptsetup: WARNING: found more than one resume device candidate:
                      ubuntu-swap
                      10147778-13f7-4a70-96ff-45635098d128

I found some other discussions/bugs about this but the authors indicate 
that the two candidates are the same.  But in my case, the 101... uuid 
doesn't exist, and the uuid for ubuntu-swap is f32...  The config file 
/etc/uswsusp.conf has the correct resume device defined (the f32... uuid 
for ubuntu-swap).

I wonder where cryptsetup is finding that 101... uuid from?  Is there an 
old config somewhere that i can update/remove that old uuid from?

Thanks

This is not upstream code, it is from cryptroot script that is added
in Debian/Ubuntu distributions only.
Seems there is a lot of legacy magic in that script though...
(See /usr/share/initramfs-tools/hooks/cryptroot which config files
are parsed to get the resume device.)

It is better to report it to distro specific bug trackers anyway.

Ah, yes, "magic". I think the story of the magician's apprentice
should be mandatory reading for all software developers.

More often than not, "automagic" turns into "auto-mess" after
a while....
