sysinst: tsubai-san says that macppc doesn't suffer from install-related
pcmcia interrupt problems. removed those for macppc
upgrade: add conditional for macppc and sparc (don't need to boot
from floppy)
- use .Ic, .Pa, .Key, .Ul, .Tn, .Sq, .Dq as appropriate
- use .Dl instead of .(disp when formatting changes are required (the latter
doesn't cope too well when font change macros are used)
- wrap .Dl blocks with .Pp
- consistently use `file system' instead of `filesystem'
- migrate macppc to common/xfer
- suggest looking in /etc/defaults/rc.conf or rc.conf(5) for rc.conf settings
- spell "separate" correctly
- use "third party" instead of "3rd party"
- move notes about /etc/localtime; sysinst does it for us
- update copyright date
Mention some new files that have appears in NetBSD 1.4.
Make i386 and arm32 X configuration conditional on those archs.
Remove pmax X11R5 discussion - uses X11R6 now.
