freebsd/etc/rc.d/sshd
Florent Thoumie 3081bf98bf Backout this commit since it breaks startup and some scripts in
certain conditions. I haven't been able to find a better solution yet:

    - Set a two read-only variables (${prefix} and ${etcdir}). This is
    especially useful when using /etc/rc.d scripts with third-party
    software installed from ports.
    - Fix rc.d/sshd to work with openssh from ports using ${etcdir}
    instead of hardcoded /etc.
    - Reflect prefix/etcdir changes in rc.subr.8.

        src/etc/rc.d/sshd: rev 1.9 -> 1.10
        src/etc/rc.subr: rev 1.51 -> 1.52
        src/share/man/man8/rc.subr.8: rev 1.11 -> 1.12
