Hello, Solaris has something called tmpfs. Some ppl wanted it under linux.
An easy way to do is create ramdisk and then just mount it as /tmp. It comes out especially handy if you boot whole system in readonly mode and some programs require writable tmp (like X for its pipes).
I used to do something like
mke2fs -vm0 /dev/ram 2048 mount /dev/ram /tmp
and it used to work like charm. However, unfortunatelly, it does not work for me anymore :( Any idea what changed?
