Perhaps there could be several formats. For instance,
--list-generations would be equivalent to --list-generations=short:
generation 1 Dec. 16 2013
generation 2 May 7 2013
And then --list-generations=long would do something like:
generation 1 Dec. 16 2013
guile 2.0.7 out,debug gnu/packages/guile.scm
hello 2.8 out gnu/packages/base.scm
generation 2 May 7 2013
guile 2.0.9 out gnu/packages/guile.scm
WDYT?

Rather, I would do:
--delete-generations=3..9
It’s easier to parse and to type.
Likewise, it could even support:
--delete-generations=1month

I’ll have to disagree. :-)
There’s no such verb as “rollback”, I think, whereas “fallback” is a
valid noun (and we don’t have the choice for “fallback”, since there are
messages in the daemon that mention it.)
Now, if you had --rollback as an alias, I won’t scream either...
