[Unionfs] Unionfs append/redirect problem

[Dean Montgomery]

I am working on a diskless client for schools.

It seems that I have to delete the a file before I can use output redirects or 
appends on the file.

mount -t tmpfs tmpfs /tmpfs
mount -t nfs -o ro 192.168.0.1:/opt/i386/rootfs /rootfs
mount -t unionfs -o delete=whiteout,dirs=/tmpfs=rw:/rootfs=ro unionfs /

echo "127.0.0.1 localhost diskless2" >> /etc/hosts
*** Permission denied

rm -f /etc/hosts
echo "127.0.0.1 localhost diskless2" >> /etc/hosts
*** works fine.

Do I always have to delete the file before writing to it?
