Can anybody shed some light on this? All the filesystems in question Hello Folks, I don't have any experience with SPARCstations, but I do run a SUN3/60 here, and have come across a similar problem (though on an AT&T 3b1). It sounds to me like the /etc/mtab file has the wrong access permissions (since root's processes can read the file, root can find the mount point). The only other explaination I can think of is that the kernal is not maintaining it's tables, which would require another doconfig (rebuild). I hope this helps.
