Subject: Overload -h option to specify an optional hostname for remote access.
X-Git-Tag: SUDO_1_8_8^2~110
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c2860cce57f6e20a4070bb1366e16b0c2a0828c8;p=sudo

Overload -h option to specify an optional hostname for remote access.
This is future-proofing; no policy plugins currently support this.
