man 2 syslog klogctl is the libc name for the syslog system call. As is, we tell the kernel is is fine to spam the console (i.e. even when dbootstrap is running) as long as the priority is less then 4 (KERN_WARNING). Since we log everything to the syslog (i.e. the sysklogd proces which is why libc changed the syscall name to something less confusing), there is no need to spam the console. So 'klogctl(6, NULL, 0);' can be used to disable all printk's to console. If people want to see what the kernel has to say, (like that module foo didn't load) they can visit the syslog output on another VT, -Erik -- Erik B.
