💅 NAME 💅

guix — the manual page for guix time-machine (GNU Guix), and the version we're living in rn is 1.5.0rc1.47-fc2f5a. It's filed under User Commands in the big book of manpages, bestie, and honestly it's giving time traveler energy ✨

🕰️ SYNOPSIS 🕰️

guix time-machine [OPTION] [-- COMMAND ARGS...]

🌸 DESCRIPTION 🌸

Okay so the whole vibe here is: it runs COMMAND ARGS... but like... in an older version of Guix. Actual time travel, no DeLorean needed 🦋

And if you don't hand it a COMMAND? It just prints the path to the time-machine profile. That's it. That's the whole moment 💅

✨ OPTIONS ✨

  • -C, --channels=FILE — deploy the channels that are defined in FILE.
  • -q, --no-channel-files — stops the user and system channels.scm from loading. Inhibit them, queen 🙈
  • --url=URL — use the Git repo sitting at URL.
  • --commit=COMMIT — pin to the specified COMMIT.
  • --branch=BRANCH — use the tip of the specified BRANCH. freshest of the fresh 🌈
  • --disable-authentication — turns off channel authentication.
  • --no-check-certificate — do not validate the certificate of HTTPS servers. (careful bestie, that's the whole point of the certificate 😭)
  • -L, --load-path=DIR — prepend DIR to the package module search path.
  • -K, --keep-failed — keeps the build tree of failed builds. evidence preservation 💀
  • -k, --keep-going — keeps going even when some of the derivations fail. resilience era 👑
  • -n, --dry-run — does not build the derivations. just looking 👀
  • --fallback — falls back to building when the substituter fails.
  • --no-substitutes — build it yourself instead of resorting to pre-built substitutes.

  • --no-grafts — does not graft packages.
  • --no-offload — does not attempt to offload builds.
  • --max-silent-time=SECONDS — marks the build as failed after SECONDS of silence. the silent treatment is a fail, periodt 🤐
  • --timeout=SECONDS — marks the build as failed after SECONDS of activity.
  • --rounds=N — builds N times in a row to detect non-determinism. consistency check, love that for us ⭐
  • -c, --cores=N — allows the use of up to N CPU cores for the build.
  • -M, --max-jobs=N — allows at most N build jobs.
  • --debug=LEVEL — produces debugging output at LEVEL.
