I do not think it is related to guix-daemon and I think it is expected;
indeed it could be considered as a bug. The command-line,
guix pull --commit=xyz -p /tmp/test
writes /tmp/test/manifest using the current Guix (say manifest 4) and
not using Guix at commit xyz (say manifest 3). Contrary to “guix
time-machine --commit=xyz”.
