How can I get it not to do this? Set RAMTMP=no in /etc/default/rcS (or /etc/default/tmpfs, depending upon the initscripts version you have). This is not done by the kernel, it's done by the initscripts at startup (/etc/init.d/mount*.sh). Note that the latest version in unstable changes the default for RAMTMP from yes to no, so it'll be disabled once this enters testing (next time you restart). Or alternatively, how can I enlarge the tmpfs? I need it enlarged from anout 200M to about 2G for this week's project. Yes, that's a lot bigger than my RAM. Set TMP_SIZE=2g in /etc/default/tmpfs, or add an entry in /etc/fstab with size=2g. Note that you'll need enough RAM + swap to back this usage, so you might want to increase the swap size. As an example (perhaps a little extreme), I have 8 GiB RAM + 16 GiB swap and a 5GiB tmpfs on /tmp. This is because the default (in unstable) is 20%VM i.e. 20% of all RAM + swap.

I think you can create a file and mount that as /tmp. I'm not sure of the details. Something else to watch out for: if your tmp file is /home/mytmpfile, but /home is in its own partition, then /home will need to be mounted before /tmp can be mounted. I'm not sure if that's technically possible or not. -Rob -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
