I was wondering if we should move to supplying the binfmt info
in files of the form used by update-binfmts(8) (which is just a set
of "key value" lines), plus a minimal script to read them. That
at least gets the data (which is what distros will want to deal with)
out of the script (which is mostly of interest to people doing
local hacking, if at all). I'm guessing that distro-specific
format registration handling will be easier to do by parsing data
files than by trying to work with a script.
