IMPORTANT: Avoid Runlevel 2 with a Partition Mounted via NFS
You should not use runlevel 2 if your system mounts a partition like /usr via
NFS. The system might behave unexpectedly if program files or libraries are
missing because the NFS service is not available in runlevel 2 (local multiuser
mode without remote network).
To change runlevels while the system is running, enter telinit and the corresponding
number as an argument. Only the system administrator is allowed to do this. The fol-
lowing list summarizes the most important commands in the runlevel area.
telinit 1 or shutdown now
The system changes to single user mode. This mode is used for system maintenance
and administration tasks.
