Of course, both stopping and restarting openssh are NP on my CentOS 5.2 box
as follows;

[root@example.com sumtec]# chkconfig --list | grep ssh
sshd               0:off    1:off    2:on    3:on    4:on    5:on    6:off

[root@example.com sumtec]# chkconfig --del sshd

[root@example.com sumtec]# chkconfig --list | grep ssh

[root@example.com sumtec]# chkconfig --level 2345 sshd on

[root@example.com sumtec]# chkconfig --list | grep ssh
sshd               0:off    1:off    2:on    3:on    4:on    5:on    6:off

It seems your customer could know this solution well.
