My apologies if this isn't the correct forum for this . . .

Our customer desires to have Integrity Measurement Architecture (IMA)
values follow across NFS mounts.  The linux kernel now supports xattr,
but only for user.* attributes.  We've modified this to support
security.ima, but in doing so we've noticed that the xattr support in
NFS is very specific to user.* attributes.  Was this done for a
reason?  Is there a reason security.ima wasn't included?

Please advise . . .

Regards,
Jeff Hunter
