(roll-back)[switch-link]: Use it.
(guix-package)[process-actions]: Always choose NUMBER + 1 for the new

behavior.

* guix-package.in (roll-back): Check whether PROFILE is valid using
`file-exists?'. When NUMBER is zero, just emit a notice. When
PREVIOUS-NUMBER is zero and PREVIOUS-PROFILE does not exist, build the

* doc/guix.texi (Invoking guix-package): Document the new behavior.
* doc/guix.texi (Invoking guix-build): Make it clear that `guix-build'

Use it instead of using `find-packages-by-name' directly.

(profile-number, roll-back): New procedure.
(show-help): Add `--roll-back'.

among OPTS, and call `roll-back' if it is, followed by a recursive
call to `process-actions'. Emit the "nothing to be done" message only
when INSTALL or REMOVE is non-empty.

otherwise nothing ends up in `out' as a consequence of commit a06a99f.

symlink if it doesn't exist yet.
