yesterday,  thought I would share the<br />
article, I see 4.1.4 stuff float around here from time to time.<br />

An excellent write-up.<br />
<br />
At Digex in the 1990s, where we were maintaining a few thousand Sun<br />
machines, we maintained the "Digex standard load" of SunOS4. It<br />
contained all of our local patches and configurations, got rid of NIS<br />
and other bad ideas, installed local builds of a few hundred packages, etc.<br />
<br />
It was an "all karch" load. We replaced /usr/kvm with as symlink to<br />
/usr/kvm-sun4, /usr/kvm-sun4c, or /usr/kvm-sun4m. OS copy scripts<br />
created and copied the filesystems, created that symlink as appropriate,<br />
took care of the bootstraps and the karch-specific kernel. The<br />
filesystem copies were done with async writes turned on. It all worked<br />
very well; we could have a new system up and running in about ten minutes.<br />
<br />
The standard load machines (sparc-proto.digex.net and<br />
m68k-proto.digex.net, would be called "golden" nowadays) were air-gapped<br />
and kept in cipherlock room. We would occasionally physically connect<br />
them to the network to do rdist runs for installation of new software<br />
and md5 comparisons of files. (that was one of our local modifications<br />
to rdist, along with Kerberos integration)<br />
<br />
We did the same thing with 68K-based machines, with /usr/kvm-sun3 and<br />
/usr/kvm-sun3x.<br />
