Hi, Is it possible to build guix packages or derivations from inside a container created by `guix system container`? When I try to, I get the following error. Is there any way to work around this? --8<---------------cut here---------------start------------->8--- # guix build hello guix build: error: remounting /gnu/store writable: Operation not permitted --8<---------------cut here---------------end--------------->8--- My specific use case is that I have the Laminar CI service running in a guix system container. From within the CI job (which is just a regular script), I wish to invoke guix to create and build certain derivations. Thanks in advance! Arun
