src/sbin: Makefile
Added Files:
src/sbin/devpubd: Makefile devpubd-run-hooks.in devpubd.c
src/sbin/devpubd/hooks: 01-makedev
Log Message:
add the device publish daemon, written by jmcneill@.
listens on drvctl for new devices and invokes MAKEDEV for them.
missing:
- manual page
- rc.d script
- more testing
but it works well enough to make new disk nodes appear in /dev when
netbsd sees them and they're missing. you will need to make sure
you have a new /dev/MAKEDEV for this to work properly (postinstall
should handle this normally, of course.)
thanks jared!
