Ping, everyone? This issue still exists. AFAICT systemd is relying on a really old tool, that that really old tool (setfont) is sometimes delaying boot by a very large amount. Can we either fix the tool (Alexey) or stop using it (systemd people)? --Andy _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
