I don't disagree there.  In general, when I need to, I tend to mount by
label rather than UUID. ;)

Ah, but that isn't a property of hibernation (as such) but, rather, of
your running mkswap on the partition you used for hibernation.

The UUID in the swap partition is dead-stable until something (like the
user) rewrites it.

I will readily agree that mount-by-UUID can be inconvenient if you are
developing or testing software that requires routine reformatting of
your swap partition.

You should probably mount your swap by label and assign a consistent
label to the device. :)

My understanding was that gparted handled all that stuff.  Am I wrong?

Likewise I thought that the KDE disks and file systems module, in System
Settings, was able to handle formatting and mount entries correctly.

I confess that I just do it the old fashioned hand-hacked way when I
need to, so I may be misinformed on the capabilities of the software.
