Description of problem:
openssh configuration file /etc/sysconfig/sshd says that it supports the f

# AUTOCREATE_SERVER_KEYS=RSAONLY
# AUTOCREATE_SERVER_KEYS=NO
AUTOCREATE_SERVER_KEYS=YES

But the init script /etc/init.d/sshd seems supports only YES and NO options, e.g. create all or none.

Please note that this may cause troubles in FIPS, where DSA should be disallowed.

Version-Release number of selected component (if applicable):
openssh-5.3p1-94.el6

How reproducible:
always

Steps to Reproduce:
# rm -f /etc/ssh/*key
# grep ^AUTOCREATE_SERVER_KEYS /etc/sysconfig/sshd
AUTOCREATE_SERVER_KEYS=YES
# service sshd restart
