Filesystem explanation

Hey everyone, I just need some clarification on a filesystem question that's been bothering me. When checking df- k (output below) you can see the root filesystem, usr, var, and the disks they are mounted to at the top of the list. However below there appears to be another root filesystem (/dev/rootfs) that is mounted on /SMSCLN. Can anyone explain what this might be?

Code:
Filesystem    1024-blocks      Free %Used    Iused %Iused Mounted on
/dev/hd4          1048576    958168    9%     1419     1% /
/dev/hd2          2097152    751988   65%    18351     4% /usr
/dev/hd9var        524288    457312   13%      771     1% /var
/dev/hd3           262144    249084    5%      396     1% /tmp
/dev/hd1           524288    505952    4%       59     1% /home
/dev/rootfs       1556480   1201888   23%      840     1% /SMSCLN
/dev/homefs       1048576   1014448    4%      589     1% /SMSCLN/HOME
/dev/logfs        3047424   2353932   23%      932     1% /SMSCLN/LOG

Thanks for the help!

/dev/rootfs is just a arbitrary name someone used for the logical volume when creating the file system. the file system is actually /SMSCLN. unless your the system admin I would ignore it Smilie

Thanks for the help, I'm not the system admin - but it's a system that I work on semi-frequently so I was just curious.
