qemu images seems big to package.
in guix we can make non-substitutable packages.

not unrelated at all.
the guix way for qemu images would be packaging trisquel from
debootstrap, parabola from pacstrap, ...

it is an opt-out whitelist implementation, i sketched it at [1].
in guix we can make a package not directly installable, but use it as
a dependency for other packages; so it would go to the store but not
to the profile and remain out of $PATH.
in parabola we can make the executable install to
/usr/exitingfreedistrofrontier and remain out of $PATH, but it would
need to copy the executable to every game package or make a pacman
wrapper to make it not directly installable.

i think skipping the documentation and using a general-purpose search
engine like duckduckgo is quite common.
making the user install some other packaged free software and execute
a command like "PATH=$PATH:/usr/exitingfreedistrofrontier/wine/" could
warn much better.

not sure[2]

looking up in dag, there's three kinds of packages:
useless in freedom: ndiswrapper.
mostly useless in freedom: wine.
useful in freedom: qemu.

useless packages should be removed.
making a opt-out whitelist for mostly useless packages seems the better option.
useful packages should get a opt-in whitelist.

mame should be classified for each architecture:
i386 and z80[3] are useful as development tools replacing current hardware.
obsolete architectures are useless if only nonfree software depend on
it, mostly useless otherwise.

[3]z80's are still produced
