I'm seeing an error concerning some daemon script at boot-up. Unfortunately it flies by too fast for me to catch what it says.

From searching the web, I have understood that bootlogd could previously be used to write a file to /var/log, but it doesn't seem to work since the Debian update to Jessie.

Are there any ways for me to get a clear log of the boot-up screen?

If I am not mistaken (have no raspbian right now) Jessie runs systemd for logging. The journal could be querried using the utility journalctl. See man journalctl for usage.

It is advisable to obtain root privileges or use sudo to get full access to system logs. As per man journalctl:

All users are granted access to their private per-user journals. However, by default, only root and users who are members of a few special groups are granted access to the system journal and the journals of other users. Members of the groups "systemd-journal", "adm", and "wheel" can read all journal files. Note that the two latter groups traditionally have additional privileges specified by the distribution.

    Jessie does run systemd, and you need sudo to see system logs – Milliways Nov 1 '15 at 22:28
  • While any user could issue journalctl and will get some results, access to the system journal is granted only root and a few special groups. So right. – Ghanima Nov 2 '15 at 10:08
  • @Milliways Do know the exact command to view the logs in the OP? – Winterflags Nov 14 '15 at 20:13

    For starters, how about sudo journalctl? – Ghanima Nov 14 '15 at 20:14
