No, it's not exactly the same type of change, it's consolidating files
in one directory, instead of consolidating files in one file.

I've said before that my arguement has nothing to do with not backing
up /var. I certainly feel the need to backup mailboxes, and would feel
the need to backup things like print jobs if I had enough of them.

Aside from minfree, I'd count /var/crash contents as 'transient'.
There's no reason to keep them long term, and if you lose them,
it's not a major loss.

I don't have a /var/pkg. What's in yours?

Mine are in /etc, it's config data.
I don't use/care about yp, but I suspect it's config data.

By semi-permanent, I mean that they are not static, like /sbin/init,
but are not constantly changing, like /var/spool/mqueue. I find
crontabs to be very much like password file entries. (in terms
of comparing properties)

Here's my question. If a non-Unix person went looking for cron's
config files, what would make him think "/var! That's where it'll

That was my point. For such a system, if it can live with a static
/etc/passwd, it could probably live with a static /etc/cron.

I'd like to see how that could work. (sarcasm). Please tell me how
/etc/rc* and /etc/fstab would be handled.

I haven't seen any explanation for why it was moved from /etc in the
first place. Anyone?
