Hi mobile@
I need ** my laptop to call a script before shutdown,
(perhaps automaticaly too with something like 'test -e ` etc,
though perhaps the default should remain with no test)
I dont see any hooks in man shutdown or halt ?
I could hack
/usr/src/sbin/shutdown/shutdown.c &
/usr/src/sbin/reboot/reboot.c # (source of halt)
or does someone have a better idea ?
FreeBSD has a mass of scripts etc for system start up, but seems light
on close down hooks ? I seem to recall on system 5 there were table
entries for up & down for lots of things, (though I never got
on with 5, not lots of others here either, & am not advocating that route),
but is there a better way than adding a hook to system("/some_path"); ?
BTW ** What I'm calling manually before halt is my
http://www.berklix.com/~jhs/bin/.sh/umountusb
A combo of umounts of USB sticks/disks with plain dos & ufs + also
mdconfig -d & gbde detach for encrypted file system on both hard
disk & USB sticks. (When I forget to call it before halt, the
laptop hangs on USB.)
Cheers,
Julian
