Subject: [PATCH 1/2] udev: Set SYSTEMD_READY to 1 when the array becomes active
Date: Tue, 18 Aug 2015 13:51:32 +0200	[thread overview]
Message-ID: <1439898693-936-2-git-send-email-thomas@archlinux.org> (raw)
In-Reply-To: <1439898693-936-1-git-send-email-thomas@archlinux.org>

In some cases, the rules set SYSTEMD_READY to 0 in order to tell systemd
to delay activation of the .device unit. It should also be set to 1 when
the array is ready.
