While Ubuntu is starting up, the init rc commands are run. Is there a way to see their full output after the system has started?

  • Have you checked the output of dmesg or the contents of /var/syslog? Aug 13, 2013 at 17:50
  • Both dmesg and /var/syslog have syslog-generate comment, and not the output upon initialization.

Ubuntu stores the output of the rc commands run at boot in /var/log/boot.log.

  • /var/log/boot.log is exactly what I was looking for! That doesn't go through syslog, does it?

    No, it doesn't use syslog. /var/log/boot.log is created by Plymouth.

The default system log location in Ubuntu 13.04 is /var/log/syslog.

Log location settings are configured in /etc/rsyslog.d/50-default.conf

See man rsyslog.conf for more information.

dmesg is a ring buffer, so it can be that messages from the top can be overwritten by newer messages, although at 16384 messages I doubt it.

Have you tried /var/log/boot.log or /var/log/kernel.log
