...maybe, maybe not, but I finally got it started!
I took another look in "top" right after reboot, because phpSysInfo told me that memory is used by 97%...although the kernel does this after a while, I was thinking that this is the point with only 256MB at all???
However, I stopped postgrey, because this was beside mysqld the main memory-user and restartet ./setup again...after 2min. waiting on the same "...wird vorbereitet"-screen it went on.
My System has 2 domains running with a compaq 700MHZ PIII, 10GB, 256MB...is there anything I could increase performance or is this system fine like it is?
Actually, gzip takes at the beginning of the setup (changing a couple times in "top") nearly 90% cpu....
....a small question on the end: is it a security risk to leave the files include_path in php.ini for phpSysInfo on "." or should I comment that out again?
