Welcome to guix :)

Thanks!

Sorry about the rough start. Guix-land is a real adventure sometimes!


No worries. Not my first time venturing into guix-land. I'm a little bit
more prepared this time. Got a wifi-card that linux-libre supports. And I'm
more familiar with the guile language.

Thanks for specifying the command and config.scm.
Did you follow the manual?

Yes. I only authorised berlin. As I assume hydra is already authorised. Is
that assumption correct?

I suspect you did not as guix was trying to build stuff (normally we
have substitutes for almost everything if you either run init without
pulling first (=guix 0.15) or pull to a commit a week ago or so.

Getting substitutes to work is crucial if you are not very patient. The
hash mismatches are a plague brought by changes upstream which are NOT
retroactively fixed.

You can check the availability of substitutes with "guix weather".

With substitutes working and available init should not take more that 10
min on a recent machine. It would probably be a good idea to state this
in the manual.


Thanks for pointing out "guix weather". I've seen it mentioned from time to
time in the mailing list. But didn't know what it was used for. Any good
workflow to find a commit that have good substitute coverage? As from what
I understand, reading the manual. It will only check the guix version
you're running.

If you want to hack on guix you will have to update guix above 0.15.


That's my end goal. Just need to be able to install it. :)

Will try to do a guix pull, to see if that works.
