freebsd stable - Aug 2005 - MNT_NOEXEC flag set on / when PXE booting diskless on 5.4-R?

Hi all,

I've just been trying to switch one of my FreeBSD work stations over to 
PXE booting and running diskless (the system drive has died).

However, I've run into a problem in that it appears that the root mount 
gets marked with MNT_NOEXEC for some reason, which causes ld-elf.so.1 to 
barf with a message of:
Cannot execute objects on /

The error doesn't occur for all applications, and I've narrowed it down 
to be that whenever LD_LIBRARY_PATH is set, then ld-elf.so.1 falls over 
with the above message.

I saw in the archives that this issue was raised back in March, but 
there was no followup there. Message ID for that email was 
<20050331111625.GA13338@zoopee.org>; interested parties are recommended 
to dig that one up.

Does anyone have a solution to this problem? I couldn't find any PRs 
(open or closed).

Thanks in advance,
/Johny

Okay, this one's for the archive, in case anyone else runs into this 
same problem:

As Danny said, the problem has been fixed (at least I don't get the 
error message any longer). By upgrading to 5.4-STABLE I've managed to 
get the full PXE boot setup to work now.

Thanks to whoever fixed that bug :)

Cheers,
