@shepherd@fosstodon.org @Mehrad@fosstodon.org So to be clear it says something like "Calculating xxxx" but at the end it decides it doesn't need to build anything?
The most common thing is that there's something in config that means it builds a derivation each time. I think Ieure (others?) on the #guix channel know what sorts of configs cause this.
But it sounds like it isn't doing this, it's just the calculation of the graph is slow?

@futurile@mastodon.social No, doesn't build the derivation while loading the time-machine. It just takes a long time to set the environmental variables and prepare the paths for the guix profile that is made by this specific time-machine. I can put the guix files (manifest, channels,...) in a temp git repo. I have tried the same setup on two different machines and there is always a very long multi-second delay (up to 15 seconds). @shepherd@fosstodon.org
