# Sample TSM startup file, adjust to your requirements and
# call from e.g /etc/daily.local
#
# Daily (nightly) backup via Tivoli Storage Manager (IBM ADSM)
# Set up environment, wrap logfiles and start dsmc.
#
# NetBSD configuration hints:
#
#  - TSM expects ${EMULDIR}/etc/mtab to exist and be meaningful. The current 
#    suse91_base package sets up a symlink to ${EMULDIR}/proc/mounts which 
#    works on NetBSD 3 if you mount procfs in /etc/fstab like
#
#      procfs  /emul/linux/proc  procfs  ro,linux  0 0
#
#    Alternatively, make ${EMULDIR}/etc/mtab a symlink to /etc/fstab.
#  - Make sure 'passworddir' is set in tsm.sys so that the passwd file
#    ends up in ${PKG_SYSCONFDIR} instead of the shadow hierarchy.
#  - The environment variables DSM_DIR, DSM_CONFIG, DSM_LOG 
#    need to be set properly. DSM_LOG may inadvertently end up in 
#    the emul shadow hierarchy.
#  - For backing up the native filesystem hierarchy, prefix paths with 
#    '/../', or use a construct like "ln -s / /.`hostname`" to break 
#    out of the emul shadow hierarchy.
