Well, my response was shock that anyone would actually have to do that much
work to reinstall the software on an existing system! I'd just issue something like
"emerge --emptytree --keep-going world", go to bed, and expect 98% of
everything to be resolved when I got back up in the morning. A Gentoo machine
is always easier to recover than to restart from scratch (and yes, it's possible to
switch out major parts of the infrastructure, like openrc <=> systemd and
udev <=> eudev, without hosing everything or even having to reinstall any package
that doesn't depend directly on the changed one).
I kept my old system installation for twelve years (2005-2017), despite a major
hardware refresh about midway through that period, and *never* had to start over
from scratch. And the only reason I didn't just image the old root partition onto a
new drive when I set up my current machine over Christmas was that I figured it was
time to get rid of all the leftover cruft from more than a decade of rolling updates.
