THe idea is to keep the /usr partition quiet, with nothing writing
to it, except for software updates. Then /usr can me mounted readonly
for normal use. Thus rogue kernels, system crashes due to power outages,
coffe spilt on keyboard, etc, will not corrupt /usr. Backup demands
are eliminated, except for one copy. It also keeps evil people
from changing programs.

Hmm. Check permissions all around. Can you create a file there as
root? as a user?

Again, look at permissions. The permissions on /usr/tmp should be 01777,
shown as drwxrwxrwt in a ls -ld /usr/tmp

Ah! It might be simpler to just move the /var/ftp directory. (Direct attack
on the presumed villain.) If /home has space, /home/ftp could be
a win. Other Unixes start it off there. Besides copying the stuff with
the tar pipes, you will need to change user ftp's home directory to
match (with vipw or chpass).
Oh, on those pipes, it is often prudent to include tar's -p switch, which
preserves permissions and ownerships.
