[sane-devel] devfsd

[Robert Stanford]

Unfortunately i'm in a special situation, im porting SANE to the Linux 
Terminal Server Project www.ltsp.org so we can hang scanners of thin 
clients and the LTSP now use the devfs daemon. Being thin clients they 
canont save node states over reboots.

Strangely a previous build of sane (1.0.3) that I copied from a RH7.1 RPM 
and used in the same way works fine.

The symlinks permisions were (strangely enough) lr-xr-xr-x /dev/sg0
Yet the /dev/scsi/foo/bar/generic   nodes permissions were crw-r-----
Any chmod I do to the symlink affects the target, not the symlink.

Regards
Robert Stanford
