I think the goal here is to make sure that the builds that resulted from
of 1) important evaluations (releases) and 2) recent evaluations aren't
garbage collected.

<sneek> snape, civodul says: i think Cuirass should register GC roots for its
evaluations under /var/guix/gcroots
<snape> [...] How many such evaluations should be registered? If all
are registered, we'll run out of space won't we? So would it be
like the last 15 or something?
<civodul> snape: i think we'd register all of them and use (guix cache) to
automatically wipe old ones periodically [09:53]
<civodul> snape: when there's a release we could manually stash important
evaluations away so they won't be deleted
<civodul> so i'd just create one subdir for each eval say in
/var/guix/profiles/USER/cuirass/evaluations [09:54]
<civodul> and that'd contain a bunch of symlinks to both the .drv and the
outputs

I went ahead and implemented a simple version of this in commit
d4623d50edac4a6e81f5986a91c2818f5fc4965d.
Let me know what you think!
