I have an unique situation where I need to change UUID to another UUID.
I formatted it and obviously number changed... I know I need these files changed. But I cannot find anywhere on the net info about customizing UUID.

the issues: when closing the lid - the notebook does not poweroff - or shutdown

i need to change

UUID=ae33e597-0c72-4c66-9f16-6606322111c3 swap swap defaults,noatime 0
2

to this

UUID=ae33e597-0c72-4c66-9f16-6606322111c3 swap swap defaults

how to achieve that!? 

btw: see the hibernation issues i have had so far

btw - i have had some issues -. with the hibernate due to a hung up upgrade process (that was interrupted unfortunatly=)

If we use ext for it:

tune2fs /dev/{device} -U {uuid}

From man tune2fs

-U UUID

Set the universally unique identifier (UUID) of the filesystem to
UUID. The format of the UUID is a series of hex digits separated by
hyphens, like this: c1b9d5a2-f162-11cf-9ece-0020afc76f16. The UUID
parameter may also be one of the following:

clear clear the filesystem UUID random generate a new
randomly-generated UUID time generate a new time-based UUID

The UUID may be used by mount(8), fsck(8), and /etc/fstab(5) (and
possibly others) by specifying UUID=uuid instead of a block special
device name like /dev/hda1.
