Hi Everybody,
I?m testing buildroot for a personal project and is a really good tool
thanks to all people that is doing it possible.
At this moment I?m testing in a virtual machine a filesystem built
with buildroot , but I?m observing an odd behavior when I try to mount
some tmpfs all of these are being mounted in the /tmp, although my
fstab is configured to mount in other way this filesystems
Maybe someone in this list can help me to find an answer to fix it or
a way to correct it. The version used to build my environment was the
buildroot-2011.02.

Are your /var/run, /var/tmp, etc, all symlink to /tmp? This should explain
what you see.
