the horror of the day is the FHS. i know why it's Like That, but i've been dealing with issues over the past couple of days regarding which parts of the filesystem i can externalize and which ones i can't, as i want to be able to provision new roots with pacstrap whenever i want. further down the rabbit hole i discovered that sharing a /home partition isn't actually as safe as i've thought it was for years... ~/.config and ~/.local contain files that can't always be cleanly ported between roots.
