Ok, this may be a hack, but in Solaris >= 10 /lib/libc.so.1 seems to be a lofs mount to a hardware-optimised version of that file. The same method could be employed for single files, e.g. create a fs snapshot for that file and then "link" the file in the shapshot over to it's original/desired place via lofs. Not pretty - but it may work (BTW: Read http://mail.opensolaris.org/pipermail/opensolaris-discuss/2006-May/017167.html and replies) ... :-) ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) [EMAIL PROTECTED] \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 7950090 (;O/ \/ \O;) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
