I also expect that a lot of users (of m68k kernels) are never going to

understanding than me of what m68k hardware is commonly used these
days, and how constrained that is in practice.
I second that - currently bisecting to find out what makes my extremely
RAM constrained m68k system fail to boot or run anything past 6.9-rc4
(sysvinit, not systemd).
As cloud instances multiply, that small quantity of lost RAM gets
multiplied. So it appears that small systems aren't so strange, even after
they become unprofitable...
Much as I appreciate Adrian's efforts to keep up with user space
development, I won't be in a position to help with an ABI change.
Bloated m68k packages will continue to work -- given emulators that run
faster with every hardware upgrade. But how would such a distro add value?
I don't mind if Gentoo ships a separate profile for (downstream) ABI
experimentation, leaving the default m68k profile on the standard ABI.
And if Debian wants to switch ABI entirely, I won't object further, I've
said enough about the associated risks.
So I'll just reiterate that I'd rather see more collaboration instead -
1) among all small systems ports, to try to alleviate Debian's package
dependency problem
2) among all developers working on non-commercial architectures, to
improve the GCC Rust frontend
3) among all 680x0 developers interested in the NetBSD ABI
4) among all users of EOL'd hardware, so that value may continue to be
extracted from it (thanks to the efforts of Debian and Gentoo devs,
among others).
