4/35    Back in my Good Ol DOS days, i used to create a ram disk for fast
        read/write scratch space.  How would I do this under linux? -crebbs
        \_ Aren't files supposed to be cached in RAM?
           \_ Files are "cached" in RAM.  However, they must exist on disk
              first. What i want to do is create a partition of RAM, say
              /ramdisk, which i can write files too, work on and which
              will stay around untill I delete_them/turn_off_the_computer.
                \_ This is what swapfs is for.  I don't know if it
                   exists under linux or not.  Yuo can usually mount it
                   as /tmp.
                \_ Geeze, would you bozos get a clue before you give stupid
                   answers?
                   mkdir /ramdisk
                   mke2fs /dev/ram5 5000 (that's 5 megs)
                   mount /dev/ram5 /ramdisk   -tom
        \_ Why do you feel you need this? If you think it will make accessing
           files in the ramdisk faster you are almost certainly wrong. I
           suppose a ramdisk might be faster under weird situations. If you
           think ramdisks are good just because they were under DOS, don't
           bother.  --Galen
