Seems to me that keeping the default 10% of disk space to be accessible only by root is wasteful in most cases. In fact it seems that / & /usr are really the only normal filesystems where you'd really want to do that, but I can't verify that by any documentation I have. Any comments would be appreciated. e-mail is sufficient..........thanks.......mcb -- Mark Brinich voice mail(or maybe the real live thing)216 498-2821 e-mail uunet!keinstr!brinich Keithley Instruments 28775 Aurora Rd.

Cleveland, Ohio 44139-1891 You should modify the "fs_minfree" field of the super block, while the fs is not mounted, of course. In any systems we have a command that do it. For example for the hp-ux the command is tunefs. Bye. -- Marco Negri Phone : +39-2-7575242 Universita` di Milano Fax : +39-2-76110556 Dip.

In fact it seems that / & First off, try putting some returns in your posts (so the entire thing isn't on a single line. Now, as to your question. The 10% isn't really being reserved for root. The 10% isn't writable by normal users because when the UFS file system gets above 90% full performance suffers significantly. -- Conor P.
