From 808952bf6d2b7549b456293ead4728b4dbf0d89b Mon Sep 17 00:00:00 2001 From: Aníbal Limón Date: Mon, 5 Sep 2016 16:59:12 -0500 Subject: systemd_230.bb: Set journal RuntimeMaxSize to 64M as default MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit At this time systemd journald uses the /run tmpfs to store logs by default systemd uses 15% of available space [1] of the /run partition, when the space runs out journald starts to vaccum/store the logs into /var/log [1]. It causes two problems one of them is timeout dev-ttySN.device's when enable debug and use journal as systemd.log_target [2] the other is related to don't find syslog entries into the journal log [3]. This problems are now more evident because i recently enabled the systemd debug option in testimage [4]. One area of improvement will be add support in systemd journald to read these parameters from the kernel cmdline like systemd.log_target, if the support exists we could add that parameter at level of testimage.
