IMO, get out of that habit.  Junos and XR essentially don't allow that.
the only case where its useful is to make a change that will be wiped on
reboot.

else, modify a copy of rancid to run show startup as a different device
type and use a second group to collect that version.  and some separate
script to diff the two groups.
