apache serving nfs-hosted files on FC5

[Ben]

Is there a simple boolean that lets me do this? My avc errors look like:

Apr  9 11:21:50 charlotte kernel: audit(1144606910.006:153): avc:   
denied  { search } for  pid=17677 comm="httpd" name="/" dev=0:12  
ino=292243 scontext=root:system_r:httpd_t:s0  
tcontext=system_u:object_r:nfs_t:s0 tclass=dir
Apr  9 11:21:50 charlotte kernel: audit(1144606910.006:154): avc:   
denied  { getattr } for  pid=17677 comm="httpd" name="/" dev=0:12  
ino=292243 scontext=root:system_r:httpd_t:s0  
tcontext=system_u:object_r:nfs_t:s0 tclass=dir


On a related note, is there a way to see what the various booleans  
are supposed to be good for?
