Hi Bryan,

I'd like just to revisit this before we close it as invalid if that's
OK.

Could you reference me to the NFS discussion you refer to? It doesn't
quite stack up to me for the following reasons:

(i) Dumping corefile on an NFS mounted directory using  Ubuntu 12.04 on
x86 works just fine for me.

(ii) On ARM a corefile is written, it's just that it has zero length. So
security doesn't seem to be a sensible answer: either I can write to the
directory, or I cannot (if I can write zero length files I could just
fill the directory with zero-length files).

(iii) Requring root access is positively bad for security - in general
we don't want things to be running as root unless they need to be.

(iv) Usually on NFS the opposite of what you say is true: typically NFS
is mounted with "root squash" which means that if you are root you often
cannot write to an NFS-mounted directory. So I can see how it would
often be required *NOT* to run using sudo if you want a corefile to
appear on NFS directories (but as per (ii) above, in this case if you
were to run as root then I would expect no corefile, not a zero-length
corefile.


Sorry to be a pain, but I think there is more to this.
