There's no question that systemd is broken.

But those broken binaries are out in the wild. End of story.

Umm. The thing is, those broken binaries *work* on 32-bit. They were
*tested* on 32-bit. They were *shipped* on 32-bit.

And we really do want to make it just work for people to build 64-bit
kernels. It is simply not acceptably to say "hey, you have 32-bit user
land, so use a 32-bit kernel". It's not a different ABI, never has
been.

It's entirely pointless to talk about some next version. THAT FIXES
NOTHING. What's so hard to understand? This is an existing problem,
and making a v6 DOES NOT FIX ANYTHING AT ALL.

And people who bring it up as a "fix" are entirely missing the point.

Seriously.
