Back in the days when i have been working with IRIX machines, i had to find out the hard way that efs was the most fragile filesystem i've ever seen on earth. It was even more fragile than the old S51K filesystem of SVR3.x, and this means a lot! That's not to flame some{one,thing}, but just as a note that i wouldn't spend a second in any code for this filesystem. If you're serious about filesystem work, you might think about AIX's JFS. :-) That's still among the best filesystems i've seen so far. There's a German un-word these days, ``unkaputtbar''. Well, since you Americans have lent the German `kaputt', i guess you figure out what this means... (the German suffix `-bar' is about the same as the English suffix `-able'). JFS is just this, ``unkaputtbar''. You turn the machine off full-steam, turn it on again, and it happily tells you ``filesystem is clean, no check needed''. ;) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
