I use rdiff-backup to keep a copy of the latest version of all my files and compressed differential backups going a year in the past. This works great except when I have a GNOME login and a ~/.gvfs directory. These are special FUSE directories that root user cannot even enter or even lstat(), which causes an annoying error to be emailed to me every night.
I finally got sick of this and have hacked a solution, I’m not proud of it, but it’ll make the emails stop!
