Even 1.0.0 isn't obvious: $ guix time-machine --commit=version-1.0.0 -- environment guix guix time-machine: error: Git error: unable to parse OID - contains invalid characters OK, so let's try the commit hash: $ guix time-machine --commit=48aa30ce73d45dc5f126f42f01e65f1be4a9b578 -- environment guix Updating channel 'guix' from Git repository at 'https://git.savannah.gnu.org/git/guix.git'... Authenticating channel 'guix', commits 9edb3f6 to 48aa30c (6 new commits)... guix time-machine: error: commit 48aa30ce73d45dc5f126f42f01e65f1be4a9b578 is not a descendant of introductory commit 9edb3f66fd807b096b48283debdcddccfea34bad Cheers, Konrad.
