And yet it's not just Python. The 2 bytes alignment is still the main blocker for Rust on m68k. More and more important Python packages such as python- cryptography are embedding Rust code these days.

I'm genuinely interested as I would like to put these up on the wiki. So far I haven't found any. I have used Debian's rebootstrap to create an initial set of m68k packages with 4 bytes alignment and didn't run into any problems yet. The Gentoo developers have also successfully created a chroot with 4 bytes alignment: https://dev.gentoo.org/~dilfridge/m68k/ I have tried it and it worked fine for me with qemu-user. So, if there is any software that is incompatible with 4 bytes alignment on m68k, I would like to hear about it. > > > > And I have bootstrapped Debian/m68k using rebootstrap with 4 bytes alignment > > without any problems.

Then you should point me to these problems. So far, I have only heard vague warnings but not concrete evidence that justifies your fear. In fact, I have provided more evidence for the transition to work than any of the people in this discussion that claim that it won't. Adrian -- .''`.
