Re: Package organization issue...

(I'm feeling that I'm overly negative again. Sorry. I'll shut up if
someone shows a good example of why a new mechanism for setting up
default environments is needed.)

Xterm doesn't call login to create a login shell; it calls the
shell and sets argv[0][0] to '-'. This cryptic convention is
the normal way to do it on Unix. If we change it, we'd have to
change all programs that do it.

Netpbm requires no special setup (all the commands are now in
/usr/bin, not in /usr/bin/pbmplus). MH requires that you
add /usr/bin/mh to the path, but that should _not_ happen to
all users. The only reason to keep MH in its own subdirectory
is to allow people to avoid it completely. Only people who
use MH should pub /usr/bin/mh in their path.

X11 setup is already being done by startx and xdm, no change
is required.

A reasonable path is already set in /etc/profile, anyway. Normal
packages will install their commands to /usr/bin. Special packages
will install commands elsewhere; like MH, those commands shouldn't
be on the default path.

manpath is set from /etc/manpath.config, and is read from there
by the man program; no environment variables needed, in the
normal case. Libraries don't require any special variables to
work, in the normal case. Package installation shouldn't cause
special cases, I think.
