add support for /etc/sysctl.d/

[www.google.com/accounts/o8/id?id=aitoawkbw4vdu6aaynqe8cbzdws7zvktd-esybq]

untested:

local retval s
for s in /etc/systcl.conf /etc/sysctl.d/*.conf ; do
    if [ -r "$s" ] ; then
        ebegin "Configuring kernel parameters (${s#/etc/})"
        sysctl -p "${s}" >/dev/null
        eend $? "Some errors were encountered"
        : $(( retval += $? ))
    fi
done
return ${retval}

What does this gain? Surely it's harder to maintain >1 config file?

when the fragments are maintained externally and automatically (rsync cronjobs), then yes, writing a script to merge a directory of fragments into one file is harder. i use this functionality under debian already.

I elected to parse /etc/sysctl.conf after sysctl.d as the directory could also be populated with package installed files, requiring /etc/sysctl.conf to override things if needed.
