Hi Jakob and all!

Apologies for not moving as fast as you do!  :-)

zerodaysfordays@sdf.lonestar.org (Jakob L. Kreuze) skribis:

To me the end goal was to move these =E2=80=9Ceffectful=E2=80=9D bits into =
a script,
such that both =E2=80=98guix system reconfigure=E2=80=99 and =E2=80=98guix =
deploy=E2=80=99 would only
have to run that script, locally or remotely.  That would avoid
duplicating these somewhat tricky procedures.

Now, perhaps we can start like this, and leave factorization for later?
I just want to make sure we don=E2=80=99t forget about that and let it evol=
ve
into something we have a hard time maintaining.

WDYT?

Thanks,
Ludo=E2=80=99.
