Yeah, I thought the context might not be rigth.  Anyway the behaviour
has changed.

However, there seems not to be httpd_sys_exec_t (trying above gives
"Invalid argument").  If I try httpd_sys_script_exec_t it does not work
either.

Biggest problem I just found out is that I can not send mail any more from
SquirrelMail (standard FC5 package):


type=AVC msg=audit(1149674474.840:81196): avc:  denied  { execute } for
pid=20207 comm="httpd" name="bash" dev=dm-0 ino=3440979
scontext=user_u:system_r:httpd_t:s0 
tcontext=system_u:object_r:shell_exec_t:s0
tclass=file
