I'm fighting the 'too small /boot partition' problem, and it looks like I'm going to have to either re-partition or install a larger drive (AND re-partition?). I keep seeing warnings that I should be sure to "back up important files," but excuse my ignorance — what are "important files"? Incidentally, I have about $200 worth of Ubuntu books that don't explain this, or even what to back up when you back up. Sigh.
Back up the /home directory. However, without using sudo, this fails to backup about five files (for example, a 'lock' file). Am I ok, or do I need to use sudo?
I suspect I should back up /etc. With sudo?
Where are the files for things like games and apps? Do I need to back them up?
If I'm doing a "clean install," is there any point to backing up the whole frickin' drive?
If I'm going to repartition /boot, what should I back up before I do that?
If I back up the drive, repartition, and then restore the backup, will it "restore" the old /boot partition?
Inquiring minds are flummoxed.
