Yes that is an important question!
I still don't understand by this (and other BIARCH stuff) is not a concern
for the more mature BIARCH systems (s390, x86_64, sparc, ...). But I can
find no evidence of this in the sysdeps source for those platforms ...
For powerpc64 we assume that most of the system utilities (the utilities
that write /var/run/utmp for example) will remain 32-bit. So for us making
64-bit backward compatible to 32-bit utmp is the best answer. What are s390
and x86_64 assuming?
