The conservative option would be to have it after all local disks were mounted
but before nfs was mounted.
Ie: just before, or just after the section marked:
# Run custom disk mounting function here
Actually, just after I think.
The other school of thought is to run it right after the root fs mount,
but before "mount -a -t nonfs". This has the advantage that various
filesystems (eg: msdosfs) will be found if the module file is in a strange
location. But the disadvantage is that then you wouldn't be auto rebuilding
(say) /usr/local/modules/linker.hints if /usr and/or /usr/local were on
some other fs.
An alternative may be something along the lines of:
mount root
script_save_sep=$IFS
extramods=""
IFS=";"
for modpath in `sysctl -n kern.module_path`; do
if [ -d $modpath ]; then
kldxref $modpath
else
extramods="$extramods $modpath"
fi
done
IFS="$script_save_sep"
mount -a -t nonfs
for modpath in $extramods; do
if [ -d $modpath ]; then
kldxref $modpath
else
extramods2="$extramods2 $modpath"
fi
done
... rest of stuff including nfs mounts...
for modpath in $extramods2; do
if [ -d $modpath ]; then
kldxref $modpath
fi
done
This is probably overkill, but should cover all the possibilities. (and
could do with some cleanup)
