This would help me greatly for backup of systems using Linux backup software. Currently the software (HP OpenView DataProtector) will fail to backup the system if the file does not contain lines regarding the file systems I want to backup. Ideally this would need some kernel support to handle updating of the file whenever file systems are manually mounted and unmounted. Remember that Linux's etc/mtab file is to record what is currently mounted. A simple translation of FreeBSD's /etc/fstab at module load time or system boot time is not really adequate. -----Original Message----- From: owner-freebsd-current@freebsd.org [mailto:owner-freebsd-current@freebsd.org]On Behalf Of Daniel O'Connor Sent: Wednesday, 30 June 2004 12:11 PM To: freebsd-current@freebsd.org Cc: Carl Makin; Paul Mather; Paul Seniura Subject: Re: Q's about IBM TSM (was Re: HEADSUP: ibcs2 and svr4 compat headed for history) -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On Wed, 30 Jun 2004 01:11, Paul Mather wrote: > I'm using the Linux 5.1.5.15 TSM client on a FreeBSD 5.2.1-RELEASE-p8 > system.

I wonder if it could work with an LD_PRELOAD or some other linker trickery.. ie replace open()/read()/write() with something that looks for /etc/mtab and instead opens /etc/fstab and translates it on the fly.. I don't use TSM though so I couldn't test it :) (BTW linux_devtools can be used to make something like this, I wrote one for the TeamSpeak port to hide an unimplemented sound ioctl) - -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFA4ihR5ZPcIHs/zowRAqRJAJwKsNyao2pKodg7YfcQwasdbAdf2ACeN8S8 sG8eI4DCFB04Lermz8NWFx4= =0zMe -----END PGP SIGNATURE----- _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org"
