I have recently had an incident in which my /var/mail/spool/ file grew to the size of 32G (yes, that is gigabytes), completely filling its system partition (/dev/sda2) and most of what I saw inside were Hibernate messages.
When I tried to restart my laptop, I got an error message from the GUI saying that the system was unable to start. Then I went into the recovery mode (command-line only) and was able to shell into the system. I did some du investigation and found the above described anomaly. I deleted the file and then was able to log into X11 (KDE Desktop) fine.
My question is: Why does X11 on Fedora 16 rely on non-boot device for startup? Can it be configured to only use the boot device or is X11 considered almost like any other application? I would like to be able to at least get inside my D.E. even if all other disk partitions are unusable but the boot partition is.
