Not the parent but a project (glorified Bash script) called vcsh[1] has served me well over the years for managing multiple Git repositories containing my dotfiles (separation of concerns).

Lately I have migrated some of that to Guix Home because the other half of the problem is having all the dependent programs necessary for the dotfiles installed automatically at the appropriate versions.

The latter one especially falls into the realm of tinkering. :)
