Since v129, there's --type option to use with trigger, and since v152 
the default --action is 'change'.

What is the proper, "reference" way to do coldplug now ? Looking into rc 
scripts of few distros - some of them use both --type (to trigger both 
'subsystems' and 'devices') and --action (to force 'add'), some only 
adjust --type (so: 'devices' + 'new'), some others rely on the defaults 
('devices' + 'change').

The most complete form would be something like:

udevadm trigger --type=subsystems --action­d
udevadm settle (is this one necessary ?)
udevadm trigger --typeÞvices --action­d
udevadm settle

And, possibly later - retry any failures with:

udevadm trigger --typeúiled --action­d
udevadm settle
