 @nixinator:nixos.dev | In reply to @tnias:stratum0.org
you can provide constrains like what packages you are interested in and (optionally) their version numbers, compiler flags, etc.
then there is a sat solver (they call it concretizer) that provides a solution to the constrains. This solution is saved as a *.lock file. From a lock file you can reproduce the environment.
packages can also provide their own constraints. as in: "version x of this package needs gcc >= 9"
Is the sat solver determistic ? I’ve used them before and they were seldom determistic when things got computationally expensive . Very interesting . | 22:24:48 |
