Thx for your response Mark

I have some question again
First, i dont have /usr/local/bin directory, only /usr/local/sbin

When i try to execute first command as root:
rm -rf /opt/lampp

i become something with "cannot remove /opt/lampp : read only file system"

and second coomand:
cp -rp /KNOPPIX/opt/lampp /opt/lampp

i become: "cannot overwrite non-directory /opt/lampp/lampp with directory /KNOPPIX/opt/lampp

Any yes, i run all services in /opt/lampp directory.
When i working in chrooted mode, everything works fine.

Thanks again
