SmartOS vmadm user-script

SmartOS VMs, at least the ones using JPC images, run the script specified in the user-init property when first provisioned.

This script is run by an SMF service called smartdc/mdata.

This service has a rather short timeout.

As a result, if your user-script script takes too long, it will die on startup, and you won't really know why.

The solution is to change the timeout at the start of your user-script script, like so (borrowed from this script):

if [ ! `svcprop -p start/timeout_seconds mdata:execute` -eq 1800 ]  
  svccfg -s mdata:execute setprop 'start/timeout_seconds =  count: (1800)'
  svcadm -v refresh mdata:execute
