		I agree.  That is the really neat feature about the
rollback command.  Like I said before it has saved me more ways the one.

Not at all the same... With JunOS, I can have the changes I made running
for days, but, when some problem is later discovered I can still
rollback to the previous (or several revisions back). I can easily
compare the current config to several previous revisions, etc.

Additionally, with JunOS I can make all my changes, verify them
syntactically, compare the changes made to the previous configuration
all without having the changes take effect during the process. Then,
when I'm satisfied I have it right, I commit the configuration. If
you've ever had to play the IOS ACL rotation game, you know how
wonderful this feature is.

Cisco's half-hearted attempt to play catch-up here is woefully
inadequate.
