That is roughly what we had until recently, minus printing the exact
command. Seamlessly switching would be a big usability plus though. My
original idea was to make it possible to have two versions (distribution
and ours) installed at once, and set symbolic links in /usr/bin and
places to make the right one active. Hans sensibly pointed out that
this is likely to be tricky and error-prone, and this was his
alternative suggestion. Any thoughts? So far, given that no one has
taken this up yet, there is still time to improve.
