Re: How add user without update package

[Fredrik Salomonsson <plattfot@gmail.com>]

No problem

One tip to avoid long build hours is the find a commit with enough
substitutes.
What I usually do is to check http://cl.guix.info/jobset/guix-master, find
one with success > 1000 and pull down that commit.
For example #6182 guix → 156b7ab  1322/620/1268
run: guix pull --committ=156b7ab
Not a foolproof way of avoiding building the heavy packages but works good
enough for me right now. Not fun when you need to build icecat and the
whole rust build chain.

There is also this that was mentioned a while back on the mailing list:
https://lists.gnu.org/archive/html/help-guix/2019-02/msg00018.html
Haven't tested it myself but looks promising.
