Restoring from rsync backup
I backed up my disks the other day - thankfully as something went wrong today. Now I am trying to restore (part of) the backup.
This paragraph is optional: The something that went wrong is that my root partition (512Mb) got full some how, preventing me from finishing a downgrade that is necessary to get my X server working again (an upgrade was incompatible with my gpu). The problem is either that I installed a lot more stuff that I intended to on to /, or more likely, a weird situation that arose as a result of these installations, whereby I now have a couple of files occupying about half the partition. I cant remember their name exactly, but its somethting like /sys/devices/pci000/0000:000:01.1/resource1 ... or something. The thing is, these arent real files are they? And I cant mv or rm them (i/o error). Sigh. So Im stuck.
Anyways, I decided, after taking another backup of the now useless partition, that I would restore it from the / backup of two days ago. So I simply did rm -r * on the root partition and rsyncd the contents of the backup into place on the now empty partition (this was all done using a live cd).
I had hoped it would be that simple, but now I cant boot. I get a kernel panic (cant read the full message cos it powers off too quickly).
What can I do to restore my backup and get running again?
