[Nate Smith]

So I went to run a yum update..

root at host:/root# pkg update
            Packages to update: 307
       Create boot environment: Yes
Create backup boot environment:  No

pkg: Insufficent disk space available (426.36 MB)for estimated need (476.64 MB) for Root filesystem

So I did a df and this is my first line

root at storm3:/etc# df -k

What is with that first line? Anyone ever seen this before?

Here's my vfstab

root at host:/etc# cat vfstab 
#device         device          mount           FS      fsck    mount   mount
#to mount       to fsck         point           type    pass    at boot options

swap            -               /tmp            tmpfs   -       yes     -

Baffled here. Any help appreciated.
