RetroGrid Rescue

An emergency roll-back of a failed update.

Sometimes, you do an update and you really wish you could just go back in time. You want to do a `dnf distro-sync` to some past repo state but you can't because you didn't mirror your own files.

That's where Retrogrid Rescue will come in. We are developing the technological back-end for the below:

# Install the Retrogrid Release
dnf -y install https://repo.retrogrid.io/retrogrid/

# Register your host with RetroGrid. Forever free tier!
retrogrid-register

# Switch to RetroGrid Mirrors
retrogrid-replace-repos

# Let's go "back in time" a week:
retrogrid-set-day 2026-05-09

# Do your rollback
dnf repo-sync

# Want to go back to the normal almalinux repos?
dnf -y swap retrogrid-almalinux-repos almalinux-repos --nobest --disablerepo='retrogrid*'
dnf remove retrogrid-release
