Would it not be simple to create say, GENERIC-64M, GENERIC-128M,
GENERIC-256M (or small medium large, or whatever), tune a number
of critical parameters, and just ship them as part of /bin? Surely
the code to have the installer check the sysctl for the amount
of ram in the machine and hard link that one to /kernel would
be trival, and at least give us something. Just by changing a
few memory settings and making a "guess" about maxusers (and
the cascade of changes that has) based on total RAM would be a
crude but useful start.
