Not much of a trouble this one - just install sysutils/sysbuild and
sysutils/sysupgrade; by default your build will carry on overnight, in
the morning you can upgrade to the latest -current (sysupgrade -auto),
just be careful with the etcupdate answers. I have been using these
since they became available in pkgsrc and have had (almost) no trouble
(on a rare occasion when vital system shared libraries have been
obsoleted and removed, the sysupgrade process may not complete and you
may have to repeat it; so far it has never come for me to a point
where I had to boot singe-user and recover manually the system).

The entropy problem for me also was solved when I realised I have to
use 'shutdown -r', as I also was in the habit of using 'reboot'.  I am
sure you have watched https://youtu.be/57z9BO95cEc - in my view, this
is necessary if one is interested in NetBSD.

The only (minor) problem I am still having occasionally is with cmake,
which hangs for me in two well-defined and repeating spots when I am
doing pkg_rolling-replace (the build completes when I attach to the
cmake process with gdb and just quit it). This has been discussed
before, I still am not clear if this is entropy related (unlikely as
it occurs always during the build of two particular packages only), a
problem with threads or an internal cmake bug.

P.S. If you are using NetBSD on a laptop with a Synaptics touchpad
there were a few recent updates in the driver and in the Xorg
capabilities, which made it really useful; only for this it would be
beneficial to upgrade to 9.99.92, as it is right now.
