Actually, the original profile, which contains ‘guix’ and its channels, *is* available in the environment: --8<---------------cut here---------------start------------->8--- $ guix time-machine -C <(echo '(cons (channel (name (quote guix-hpc)) (url "https://gitlab.inria.fr/guix-hpc/guix-hpc.git";)) %default-channels)') -- shell -CW coreutils [env]$ readlink -f $(type -P guix) /gnu/store/42731vcvzl6nrwa584mziwhpvp4xs72r-guix-command [env]$ type -P guix /gnu/store/ca142m4lm0grxmsjqrcqpfl5qb5i1rka-profile/bin/guix [env]$ readlink $(type -P guix) /gnu/store/j5g09kjd7pv1b6919vbsnjs160xfw9md-profile/bin/guix [env]$ /gnu/store/j5g09kjd7pv1b6919vbsnjs160xfw9md-profile/bin/guix describe guix cbd20d6 repository URL: https://git.savannah.gnu.org/git/guix.git branch: master commit: ]8;;https://git.savannah.gnu.org/cgit/guix.git/commit/?id=cbd20d627497053871db863970c07d93c7081786\cbd20d627497053871db863970c07d93c7081786]8;;\ guix-hpc 887d76a repository URL: https://gitlab.inria.fr/guix-hpc/guix-hpc.git branch: master commit: ]8;;https://gitlab.inria.fr/guix-hpc/guix-hpc/commit/887d76a8e1d0f35d615c613b28b9b871f39a997e\887d76a8e1d0f35d615c613b28b9b871f39a997e]8;;\ --8<---------------cut here---------------end--------------->8--- The problem is the extra profile layer that confuses ‘current-channel-entries’ in (guix describe).
