This was discussed upstream a while ago: http://lists.freedesktop.org/archives/systemd- devel/2014-April/018378.html
A simple "debug" indeed enables debugging for everything. If you want only systemd debugging, use systemd.log_level=debug, if you want only kernel debugging, use "loglevel=debug". See also "man kernel-command- line" or "man systemd". I really don't want to deviate from upstream for this and break existing documentation. ** Changed in: systemd (Ubuntu) Status: New => Opinion -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1402039 Title: systemd spams kernel log with debug kernel cmdline option To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1402039/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
