<rekado>and if I already have Guix I could use the server that prepares the Guix environments as a substitute server
<rekado>so I’m doing this now: one server has an EBS volume on which Guix is installed. That volume has a snapshot, so that all the user VMs that are generated can quickly instantiate a copy — so they have Guix.
<rekado>it’s not the *same* Guix, but that’s okay.
<rekado>they then authorize the main server as a substitute server and download substitutes only from there.
<rekado>they will always get substitutes right away, because the environment has previously been prepared.
<rekado>the only annoyance is that the manifest has to be computed twice, but it makes for nicer copying without involving tar or SSH.
<civodul>not sure what, but there's something to do about this pack/copy story
