+Subject: [PATCH] units: disable start rate limit for
+ systemd-vconsole-setup.service
+
+The unit will be started or restarted a few times during boot, but but it has
+StartLimitBurst = DefaultStartLimitBurst = 5, which means that the fifth
+restart will already fail. On my laptop, I have exactly 4 restarts, so I don't
+hit the limit, but on a slightly different system we will easily hit the limit.
+In https://bugzilla.redhat.com/show_bug.cgi?id=2251394, there are five reloads
+and we hit the limit.
+
+Since 6ef512c0bb7aeb2000588d7d05e23b4681da8657 we propagate the start counter
+over switch-root and daemon reloads, so it's easier to hit the limit during
+boot.
+
+In principle there might be systems with lots of vtcon devices, so let's just
+allow the unit to be restarted without a limit.
+
+Fixes https://bugzilla.redhat.com/show_bug.cgi?id=2251394.
