I recently upgraded from 2.2.6 to 3.2, which shouldn't be too different
to 2.2.5 to 3.2. What I did was NFS mount /usr/src and do `make
aout-to-elf-build', then `make aout-to-elf-install'. (I know I
could do these in one step, `make aout-to-elf', but I like to do it
separately.)
It wasn't flawless for me though, but there were only minor problems. I
think the main thing I forgot to do was upgrade /etc before rebooting,
which meant that the ELF libraries weren't set up by ldconfig (or it
might have been the a.out libraries, I can't remember). If you upgrade
/etc/rc* (being careful not to clobber any changes you've made), and do
`make aout-to-elf', you *should* get a working 3.2 system. There's no
guarantee though, something could go wrong, so it would be a good idea
to try it on a non-production system first.
