[ILUG-BOM] What is supermount ?

Hi all,

With allmost all the distros (except Slackware) which use the new 2.6 kernel, I see a fstab entry for removable medias (Cdrom/Cdwriter, floppy, etc.) like this,

/dev/scd0 /mnt/cdwriter supermount fs=iso9660,dev=/dev/scd0,--,ro,iocharset=iso8859-1 0 0

What is supermount ? When I tried this with Slackware (with kernel 2.6.7 included under "testing"), the kernel says "file system supermount not known". I read the man pages for mount, but does not mention any such thing. Nor does any documentation with the kernel sources. I feel that this is something like autofs, but didn't dvelve much into it.

Clues/Hints/Did I miss something ?

Regards, Rajen.
