A wild guess :

cp -r /tmp /tmp2
umount /tmp
cp -r /tmp2 /tmp
rm -rf  /tmp2

When you have root filesystem on usb you can do:

mkdir /tmphdd
chmod 1777 /tmphdd
cp -R /tmp/* /tmphdd
mount --bind /tmphdd /tmp

it works for me :-)

I haven't used "mount --bind" but I'm still worried about this approach. In the default configuration, /var is a symlink to /tmp, so there are several files there almost as soon as the system starts. You can copy them, but if any are open (in use by a running program), the program will write to the *old* file, not the new one.

On my system, that's dnsmasq ( /tmp/dhcp.leases ) and syslogd ( /tmp/log/messages because my /etc/init.d/boot runs "syslogd -m 720").  Be *very* careful about moving entire directories after the system is up and running!

my system writes to the new /tmp/dhcp.leases. I have uptime 2 days 54 min after I did that mount --bind and no problems. Maybe some will appear with time.

And even if the system will write to the old file (which still exists in ram), so what?

The discussion might have continued from here.
