[Nikola Simidzievski]

Hi,
This change boots the system, but none of the services is started. Here is
an output:
===========================================
....
touch: cannot touch `/var/lock/subsys/rsyslogd': No such file or directory
Starting sshd:                                       [touch: cannot touch
`/var/lock/subsys/sshd': No such file or directory

MySQL Daemon failed to start.
Starting MySQL:                                      [FAILED]

touch: cannot touch `/var/lock/subsys/local': No such file or directory
