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.

Umount /usr/local & make sure the permission on /usr/local (mount point)
is r-x to all.

Can anybody shed some light on this? All the filesystems in question We had a similar problem on an RS/6000 using local mounts. The problem turned out to be the permissions on the directory before the mount were less than the permissions after the mount. -- | Email - !uunet!ulticorp!ultixrs!rick Rick Poleshuck | Voice - (201) 887-9222 Ext. 755 | Mail - The Ultimate Corporation, East Hanover, NJ 07936
