Well, with either "B" or "C" you don't need any symlinks just so long as
you don't need to do anything special to meet special requirements (such
as diskless operation, or whatever).

I agree, but you must realize that /usr/pkg/etc files need not be
physically separate from the rest of /etc either. It is quite possible
to have full segregation (with easy management of that segregation) and
at the same time store those files on the very same physical medium, and
perhaps even in the very same logical filesystem.

I'm not so sure we do, but I see a massive difference in perceptions.
Note that I said "require storage private to a particular host in *some*
circumstances" -- the key word being "require". What I was thinking was
that in all other circumstances *all* of the storage for a given host is
guaranteed to be "private" anyway, so this requirement is met by
default. Admittedly my wording could have been better -- I did not mean
to imply that any config files should always be shared.

Indeed. It is my recollection that the "C" option suggests simply
/etc/pkg/* (and /var/pkg/*). I.e. all pkg config (and run-time) files
lumped together in one sub-directory of the "normal" config (and
run-time) directories. I certainly don't like anything that includes
the package name in the pathname, and I don't think I've ever said
anything to even suggest this possibility, nor do I recall that any
versions of any proposals put forth to date use this scheme. Perhaps
you are confusing something here with the SunOS-5 way of doing things.
Such a scheme takes segregation a little further than I think anyone
here would like.

Segregation is segregation. Either it's 100%, or it's not segregation
(at least in this scenario -- you can't segregate binaries and not
segregate their associated files and claim that you've segregated the
packages from the system because it just wouldn't be so).
Both the "B" and "C" proposals offer segregation. The "B" proposal is
the most elegant and orthogonal, at least in my opinion, and the "C"
proposal offers to avoid necessary symlinks in a few more circumstances
while at the same time associating like files under the same
*I* am not afraid of a couple of necessary symlinks, and if I want to be
rid of them then I will simpy integrate everything into the one true
hierarchy. I.e. if you don't like symlinks then you have the option of
There is no option which includes keeping the cake forever and eating it
at the same time.
