*&()(*&^$#@!!!!!!! Argh!!!!!!
Sigh... Ok, I feel a *little* better... Without this patch the way
things are now loading either kde or gnome during the initial install is
enough for the install to end quite abruptly complaining that init
disappeared (sysinstall runs as init during installs).
This is hopefully just a band-aid but while discussing this Kris
mentioned the 128M limit could cause some pkg_add based stuff problems
now-a-days so I don't feel too bad removing these limits.
That said, sysinstall's memory usage becomes completely insane as it
loads packages - I'll start trying to find out what's really causing it
to bloat. Before now I really didn't have a concrete idea what was
causing the installs to terminate that way (the sysinstall environment
is a bit hostile to work in, and having it blow up so spectacularly that
its init was gone wasn't an overly helpful clue...).
To give you a feel for what I mean by "insane" if you install kde,
gnome, and a handful of other packages the sysinstall process bloats to
around 610Mb size...
