@tost @samgai yay we found an even shorter solution! another win for lateral thinking :meow_party:
i learned a lot through the way, all thanks to you :02superblush:
don’t forget to do something like ${ID=$ID_LIKE}
hmmm yea you wrote "${ID:=$ID_LIKE}" originally i’d write "${ID_LIKE:-$ID}“ ie: if ID_LIKE exists use that, bc is the family, if not use ID, because that will be “mommy distro”, and the :- because i don’t want to override ID_LIKE
