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. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request@tmbg.org, www.tmbg.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
