>#!/bin/sh
>#
># Wrapper script around /usr/sbin/hald-subfs-mount to fix some of the mentally
># deficient aspects of that script. Mainly, to change mount options.
># This is not a solution, just a workaround.
># A solution would be to actually read the volume.policy.mount.option.*
># hal settings, but all that hal stuff is annoyingly complex (and badly
># documented). Perhaps a better solution would be to read /etc/fstab,
># like everyone expects since the beginning of time.
>#
># How to install:
>#  1) mv /usr/sbin/hald-subfs-mount /usr/sbin/hald-subfs-mount.orig
>#  2) Copy this script to  /usr/sbin/hald-subfs-mount
>#  3) chmod 755 /usr/sbin/hald-subfs-mount
>#  4) Review the mount options you want to use
>#  5) If you want to change anything, or see what's going on,
>#     uncomment (or set) the DEBUG and ERROR variables.
>#  6) This script supersedes the method given in the SUSE 10.0 release notes
>#     for turning off the "sync" mount option!
