mod6: (to pull in 'bzcat')
mircea_popescu: why is this required though ? is it just because random idiots decided they need a SPECIAL rar for their ever so special code farts ?

trinque: thought it was buildroot asking for bzip2
mod6: it looks to me that ya, buildroot needs it.
mod6: i don't think that because they used to bundle up the kernel as a bzip2 that means that average orc-os wouldn't have that tool set in the default userland,.
mod6: seems to be two seperate things.
mod6: oh,.. i see what you might be getting at. buildroot doesn't come with it because yadda yadda, no kernel needs that to unroll.
mod6: anyway, yeah, someday we'll get away from this wad.
