User:Johannbg/QA/Systemd

Systemd is a system and session manager for Linux, compatible with SysV and LSB init scripts. systemd provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux cgroups, supports snapshotting and restoring of the system state, maintains mount and automount points and implements an elaborate transactional dependency-based service control logic. It can work as a drop-in replacement for sysvinit.

Quick Debugging Tips

• add "systemd.log_target=kmsg" to the kernel command line to let systemd buffer
• to be written to the kernel log buffer to kernel buffer
• Run dmesg from the command line to inspect systemd output
• Redirect dmesg ouput to a file for later inspection or to use as an attachment to a bug report
• run /bin/systemd --test --running-as=init from command line to test run init as systemd.
