All make sense. Thanks for explaining.
As said, my preference of such thing is “guix gc” and not “guix pull”.
But since “guix pull --delete-generations” is already here… it pulls by
deleting. :-) Anyway, it is “guix pull”.
However, I still do not like the “automatic” part. Personally, I would
prefer something like:
guix pull --delete-generations=2m
deleting the cache older than 2 months, in addition to the old profiles.
Because, with your patch, if I want to change the expiration or the
period, it is not convenient: via channels.scm, maybe.
Sometime, I am one or two months off (vacation). And I am sure to
forget to tweak the channels.scm when I am back. Well, I have 3-4
channels.scm files; for example I am not pulling guix-past each time I
pull. Therefore, I should have these 3-4 channels.scm duplicated with
the expiration+period tweaked for when I am back from long breaks.
Well, if the automatic is the default, a way to turn off could be nice,
at the CLI level or even globally. IMHO.
Cheers,
simon
