Subject: [PATCH 03/22] host/rootfs: generate virtiofsd services
Date: Mon, 10 Oct 2022 23:28:43 +0000 [thread overview]
Message-ID: <20221010232909.1953738-4-hi@alyssa.is> (raw)
In-Reply-To: <20221010232909.1953738-1-hi@alyssa.is>
The approach of having a template service for each virtiofsd comes
from the work I need on Wayland support for Unikie, hence the Unikie
copyright in etc/s6-rc/ext-rc-init/up.
