Those saying this need to offer alternatives.

ext2fs is piss-poorly documented where we got the Linux bits from what
had to be done to make then work for us. I have up after an hour trying
to get the right sys/gnu/ext2fs/sparc64-bitopts.h. So I don't think
anyone is going to do it anytime soon. I'll just move it to
sys/{i386,alpha}/conf/NOTES

"meant" != is. The work to make it truly MI is immense.

I doubt bt(4) will work on sparc64, PowerPC, or IA-64. So do people want
all that's in NOTES.bt (and that's a lot of docs) to be duplicated three
times in sys/{alpha,i386,pc98}/conf/NOTES or split out as I have??
