Re: How to take down a system to the point of requiring a newfs with one line of C (userland)

Did you actually bother to read his report?

While his example is used "/", if the report is
correct then you
just need to replace "/" with the path of any file
system mount
point that is world writable like say "/tmp".

Do you have /tmp mounted like this?
/dev/ad0s4e    507630   162050   304970    35%    /tmp

Have you tried using "/tmp" or some other suitable
mount point
before slinging off with the old Doctor joke?

Even if it is only "/", having the system die and
not be recoverable
due to having a excessive number of files in "/"
is a critical
error.  I'm sure you have *never* accidently copied a set of
files
to "/" in your life.  Me, I know I've made that
sort of mistake in
the past, and as I'm not perfect, I'm sure I'll make that
sort of
mistake at some point in the future.  I would however like
the
machine not to fallover when I do make that mistake.

Now why don't you be constructive and verify whether the
report is
valid or not.  I don't have a spare machine to test it on so
I'm
not going to attempt it.

Hi,

  I would agree with Mark and Jim, this is a serious issue
for enterprise
servers. Yet another example where I would have wanted to
see a more
supportive response from the FreeBSD project members, like
Robert Watson
just did. This would benefit keeping a good relation with
the business
users.
