[RndTbl] Removing old kernel images

[Sean Walberg]

When I see a system run out of inodes, it's usually because there's some
directory full of little or zero length files there somewhere.


I didn't learn this until recently but Linux will store the file contents
in the inode itself if it's under a certain size (around 60 bytes). So it's
possible that you don't even notice the space drain until you run out of
inodes.
