Hi Guix!
During the Guix days we talked about the graphical installer and more
specifically about the recommended partition size to host the store.
Question for everyone:
How much do you allocate to the store?
I don't think that a rule like "10% of the disk" is really what we
need. The store "recommended size" does not grow linearly in my
understanding (but I could be missing a point).
I've tried with 25GB: it's way too painful.
Alex Kost once told me that he used 50GB and needn't `guix gc` for about
a year.
Too small a partition for the store can lead to a painful Guix
experience. We don't want to frustrate newcomers.
Frustration typically occurs when the partition is full and the
user must run `guix gc`. Running `guix gc` can lead to packages being
re-downloaded, etc. This is even more painful on slow connections.
Of course, we all make different uses of Guix and the rate at which the
store gets filled may vary a lot from user to user. It seems hard to
"recommend" something universal. Let me try anyways:
"How much space to we need so that the store does not get filled
before a year with a default desktop.scm (with GNOME?), running weekly
updates (i.e. about 52 times)."
This will take some time to measure ;)
I'm not sure we need to partition at all: is it a problem to use the
full disk? If the user really wants to keep the store separate, we
could document a recommended minimum of 50GB for instance.
On a similar note, what do you think about adding hardware detection to
the installation process and help create a config.scm with the right
values for a specific machine?
Lewo from the Nix community told me they have hardware detection in
their config generation script:

What do you people think?
