A second /gnu/store? Cuirass/guix-daemon with a different partition.

A second /gnu/store? Cuirass/guix-daemon with a different partition.

[Bruno Victal]

Hi,

I'd like to give Cuirass a try as it seems to be a better way to deal
with package rebuilds and it isn't very practical to handle these in the
same computer I'm using to hack on Guix. 🙂

I have a headless computer that's also running Guix and it has the
following storage layout:

[SSD] → /  /gnu/store  /boot/efi
[SSD Ⅱ] → /home
[HDD] → (not yet formatted)

The capacity of the SSD holding /gnu/store isn't big and is
geared to be used as a fast OS drive.

The HDD has ample storage space and it's this drive that
I'd like to use for storing the builds from Cuirass.

Does anyone have any insight in how I could spin a Cuirass service
or guix-daemon that can be made to use an independent “/gnu/store”
located in another drive/partition?

Furthermore, I consider that nonfree software must be eradicated.

Cheers,
Bruno.

Disclaimer: I've never done anything with Cuirass and I know more or
less nothing about how it works.

I'd try running it inside a container (e.g. Docker) or in User Mode
Linux (if the performance penalty UML introduces is not a problem).

Then keep the container's (or UML's) filesystem on the drive/partition
you want. And configure your network to expose the necessary ports to
the outsite. Or *if* Cuirass listens on the HTTP(s) port (again, I don't
know how it works or what communication protocols it uses), set up an
HTTP reverse proxy

Happy hacking :)
