Of course,  that's all IMHO and fit for my usage:
1) Same FreeBSD, as in laptop/desktop, (e.g. really same - GENERIC kernel
is used, without dropping any kerberos or else), and yes, I know that
nanobsd can that;
2) .vmdk simply deployed into Esxi/virtualbox (not sure nanobsd can produce
3) Transparent /etc/ modifiying VS nanobsd approach (edit, don't forget
mount /cfg, copy there;)
4) Only OS, no packages included - e.g. I can upgrade/downgrade packages
without touching any byte of OS. Except for symlinks :) nanobsd specified
that if you want packages - you need built them in.

Of course differences not so big, and I'm not saying that my way is more
It just raised question deep in me - why OS still aren't modularized, and
most of it not in RO (while it should).

Something like this
