I had the pleasure of running into the overflow tmp system today 🙂 This lovely simple backup thing is misconfigured, I am aware of this, and this dumps all my junk on the fucking root. Well, not the root, but the /var/backup/ , whatever, its the root partition 🙂 And since that doesnt need to be big, it fills up REALLY quick 🙂
So the root was full & the script noticed this; kicking in & saving me with the a tmpfs thingy 😉
The script responsible for mounting your /tmp as overflow is run at boot time (it is located in /etc/init.d/mountoverflowtmp). It runs a check to see if there is a minimum acceptable space on /tmp and if there is not, it mounts it overflow. It also checks for unneeded overflow tmpfs for /tmp and removes them if that is appropriate. That is why after you freed some disk space and rebooted everything went back to normal.
Its a cool system 🙂 A great step toward the whole userfriendly thing 🙂
Now if they d only have made it a bit bigger 🙂 1mb isnt much..
Still – Bloody Cool System 🙂
