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....
