So fix tar to not do silly things.
Kernel major:minor numbers are not stable.
I forgot to add: '.. not stable across reboots.'
YOU Tell that to the tar/star people, they are flabbergasted that its not
stable. It apparently is for every other OS tar can be run on.
They probably have a point with the st_dev usage.
You better find out why your major:minor pairs keep jumping around.
Simply because the 'not stable across reboot' statement holds only for
added/removed disks and maybe if the detection order changes.
If your setup relies on a certain order, make sure the drivers get
loaded in a fixed order. Its not clear from your other mails what
exactly caused it. If its only due to a temporary change in
testkernels, noone can do anything about it.
