No, /etc belongs to the user, and we can't trust that's it up to date; freebsd-update would update it, but make installworld probably wouldn't, and expecting the user to run mergemaster or etcupdate adds one more point of failure. > 3) This article has an example of a script that works on many flavors > of linux, any way to make it so that it works on FreeBSD as well? > http://unix.stackexchange.com/questions/6345/how-can-i-get-distribution-n= ame-and-version-number-in-a-simple-shell-script Same reason as above. Plus, I'm pretty sure this does not work; /etc/lsb-release on a RHEL 6 desktop looks like this: LSB_VERSION=3Dbase-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch= :graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noa= rch which is nothing like what that script expects. BTW, this grew out of a discussion in the security workgroup at the DevSummit (cf. https://wiki.freebsd.org/201309DevSummit/Security) during which we touched upon roughly the same points as you raised. This was initially meant to be little more than "echo X.Y-RELEASE-pZ" and to be used only by portaudit / pkg audit / what have you, which is why it's hidden away in /libexec, but considering how much it's grown from inception to implementation, it might make more sense to put it in a more accessible location.
