} Why not upgrade the kernel first?  In my experience that is always the
} safest way to go (and is usually safe for remote upgrades too).

    Yep.  I've taken systems from 1.6 to 4.0.1 this way without a
hitch.  Basically, install new kernel (possibly custom built) and
/boot, reboot, upgrade userland (unpack all sets except *etc.tgz), use
postinstall/etcupgrade to handle /etc, make any other changes to /etc
that are needed, reboot, rebuild packages at your leisure.  The only
failure I've had is with a botched installboot.  On many platforms, you
can simply cp .../usr/mdec/boot /boot.  Check installboot(8) to find

Somewhere in 4 -> current, the modules were introduced and I had to
actually lay my hands on the system to get it working again. I'm fairly
certain you may have to go from 4 to a monolithic 5, and 5 monolithic to
5 modular. But I'm not sure.

The big trick was to fix my SPARCstation that had no way to get a new
kernel installed. That involved netbooting fun. Hooray for upgrades.
