I just tried the following: --8<---------------cut here---------------start------------->8--- guix environment -l ... --8<---------------cut here---------------end--------------->8--- was forever until I stopped it. Then --8<---------------cut here---------------start------------->8--- guix environment --no-grafts -l ... --8<---------------cut here---------------end--------------->8--- completed in a few seconds. After this, --8<---------------cut here---------------start------------->8--- guix environment -l ... --8<---------------cut here---------------end--------------->8--- again completed in just a few seconds too. -- Pierre Neidhardt https://ambrevar.xyz/
