Yes, we walk in a DVD-ROM with a FreeBSD installation image on it. This =
works because there is a self-contained installer that contains a very =
complete system. Certainly enough to build things like file servers and =
network infrastructure machines (dhcp, ntp, other general network =
services).
Installing ports/pkgs, on the other hand, is a real pain. For pre-built =
packages, you can build a list of dependencies, download the packages to =
an external machine, copy them to a portable drive, and walk them over =
to a shared filesystem. This works, provided there are pre-built images =
of the package and its recursive dependency tree (and that they are =
configured in a way that works for your environment).
If the above doesn't work, you have to fall back to ports. And this is =
where things get really hairy. Just generating the list of required =
distfiles is problematic. 'make fetch-recursive-list' will give you a =
script to run to pull down the direct build dependencies, but this =
misses run-time dependencies. Generating that list takes a lot of =
manual work, and is *very* time consuming.
The increasing focus on securing systems from network attacks in only =
increasing the number of air-gapped environments (and I know this from =
first hand experience). The sort of massive unbundling that a few =
people are tossing around here has the potential to exponentially =
increase the workload of people operating in the environments I have =
witnessed (and worked in). I want them to realize that there are =
ramifications to those sort of changes that need to be taken into =
consideration.
These days UNIX tends to be single-user environment, for the most part. =
Because of that it is very easy for people to get into the mindset that =
"if I don't use it, nobody else uses it," and thus losing sight of the =
whole being so much greater than the sum of its parts.
That said, I can understand wanting to unbundle some of the very complex =
but lesser used components (e.g. bind). But there's always a balancing =
act to be performed here. Making every command in /usr/bin its own =
package serves nobody. (Yes, I exaggerate to make a point.)
