Running httpd scripts from nfs mounts?

[John W. Lockhart]

I'm trying to run scripts via httpd from a trusted nfs server,
but selinux is preventing me:

kernel: audit(1106703013.728:0): avc:  denied  { execute } for  pid=28425
exe=/usr/sbin/httpd name=sanity_server.pl dev=0:12 ino=32407792
scontext=root:system_r:httpd_t tcontext=system_u:object_r:nfs_t
tclass=file

So I umounted the nfs volume, and added the following to the
mount options in /etc/fstab:
  context=system_u:object_r:httpd_sys_content_t

I mounted the volume again, and re-tried.  That failed with:

kernel: audit(1106705663.904:0): avc:  denied  { execute_no_trans } for
pid=28573 exe=/usr/sbin/httpd
path=/mnt/myserver/testing-scripts/sanity_server.pl dev=0:12 ino=3
2407792 scontext=root:system_r:httpd_t
tcontext=system_u:object_r:httpd_sys_content_t tclass=file

Now, there's a lot of miscellaneous stuff on /mnt/myserver,
not just the web scripts.  I need to figure out how to get the
scripts working again (preferably without breaking anything else)...
they worked fine under RHEL3, but are failing as above under the
current RHEL4 candidate.

kernel is: 2.6.9-5.EL #1 SMP Wed Jan 5 19:23:24 EST 2005 ia64 ia64 ia64 
GNU/Linux

(The script fails on other architectures, as well; I just happened to be
using the ia64 box tonight.)

Any/all words of wisdom appreciated,
