You are right, these are (almost?) the same. Ephemeral could also be imagined without spawning a some process, but also without registering a "root". But this would not work, since as soon as one runs "guix gc" while such an environment is active, the environment would be destroyed. -- Regards Hartmut Goebel | Hartmut Goebel | h.goebel@crazy-compilers.com | | www.crazy-compilers.com | compilers which you thought are impossible | --------------02B187AB02225824D43A134C Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: 7bit

How is this different from the ephemeral vs. persistent dimension?
Creating an ephemeral package set makes sense only if you spwan a
process in it (not necessarily a shell).

You are right, these are (almost?) the same.

Ephemeral could also be imagined without spawning a some process, but also without registering a "root". But this would not work, since as soon as one runs "guix gc" while such an environment is active, the environment would be destroyed.
