Nothing. But if you want it persistant you have to put it in loader.conf or= =20 sysctl.conf, depending on the kind of sysctl (loader tunable or runtime=20 tunable). > > Additional info: > > $: more /etc/devfs.conf > <snip> > perm acd0 0660 > link acd0 cdrom > > Speculating, I assume that the BUGS section of sysctl.conf(5) applies, > somehow. Hmm, what's your problem? You can't set the sysctl or it is unset after a=20 reboot? The latter of course is true. =2DHarry > > NB: the page covering this in the FAQ at freebsd.org says run this: > > sysctl -w vfs.usermount=3D1 > > The man page for sysctl on 5.4 says this: > > COMPATIBILITY > The -w option has been deprecated and is silently ignored. > > Is the -w flag only for 4.x installations? > > I'm pretty sure I'm going to see the answer to this as soon as I hit > send. --nextPart4012116.EWbaAceBuU Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (FreeBSD) iD8DBQBCsU2yBylq0S4AzzwRApBGAKCOdXYKTyt2K3jLx6ltS67zHcESSQCfS59v T0TIE0exVhxkrsuIpXudMJY= =/pxK -----END PGP SIGNATURE----- --nextPart4012116.EWbaAceBuU--
