You will create the exact same problem you want to fix: we can guess
some softwares are built on linux/m68k with 2byte alignment in mind. So
once the ABI is changed, you'll have to track them to fix them.
Could you point me to these packages which assume 2 bytes alignment? 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.
qemu-user is one of these softwares that know m68k has alignment of
2byte. All the structures translated from the m68k chroot to the host
kernel are with a 2byte alignment.
Thanks,
Laurent
