Speeding up NixOS installation by having Nix store on an external disk

okay, your prewarming the cache on the other machine… i understand now.

copy with tar should be fine, i’m overly cautious about file system copies after years of backing up / on unix servers… i need to throw this caution away…old habits, they die hard i guess.

I’m trying to work out the relationship between the sqlite db (which has a bit of state in it)… … give it a whirl…see what happens.

i think it will be ok.
