:Seldom. But the strings are still in the kernel, which becomes
:bigger with every build. My argument was more general, however,
:and directed against the growing tendency to use string literal
:(and copy them beck and forth). IMHO, the point of faster hardware
:is purely to have thing running faster, rather then letting
:programmers be "sloppier".

:However, as I already stated, this is just my preference.

You are operating under the assumption that the strings somehow
take a huge amount of space compared to an int and the rest of the
sysctl structure. This couldn't be farther from the truth.
apollo:/usr/src/sys# sysctl -A | awk '{ print $1; }' | sed -e 's/://' | wc
384 382 7555
8K. Not a big deal. And this doesn't even include filtering out the
prefixes which I'm duplicate-counting all over the place.
The equivalent 'integer' form, judging by the average length of the
postfix string, would still eat 3K, so we'd only be saving 5K.
Strings are a whole lot more portable then integer assignments.
