Raw guessing... I think it may be easier to port ResierFS than trying to get the old UFS code adjusted to do that. Or use QFS if you really want a fast filesystem. If you are just want to boose UFS temporarily it may be better to make the "fastfs" thing a mount option and then use "mount -o remount,nologging,fastfs ; do_something ; mount -o remount,nofastfs,logging" ... ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) [EMAIL PROTECTED] \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 7950090 (;O/ \/ \O;) _______________________________________________ opensolaris-discuss mailing list [email protected]
