Hello,
My /var/www and /tmp are in different filesystem.


# df
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/hda3             37980892   3907128  34073764  11% /
/dev/hda1                91556      4988     86568   6% /boot
shmi:/var/www         37980892   1694152  36286740   5% /var/www


If I use "-T /tmp", the error also occurres. Seems rsync will unlink the
original file before copy the new one over. Idea?

$ rsync -a -T /tmp home::www/pahudtestfile ./


unlink pahudtestfile: Permission denied
copy /tmp/.pahudtestfile.v4pXKW -> pahudtestfile : Permission denied
