To clearify things: util-vserver prefers to use _syscall3() (which is called 'fast' syscall invocation method in the ./configure output) when it is available. _syscall3() is often implemented with inline assembler in <asm/unistd.h>. But at least on i386, it can not be used in combination with dynamic linking as it writes to the %ebx register which is reserved for PIC addressing. Therefore, most glibc kernel-headers do not provide the _syscallX() functions overall and the 'traditional' syscall(2) must be used. Enrico
