POWhat could be the causes of "permission denied" for tty1?

Body
copied!<p>On my VPS server (Fedora 9), mingetty keeps respawning itself because of a "permission denied" error on tty[1-6], even though:</p> <pre> root# ls -la /dev/tty1 crw------- 1 root root 4, 1 Sep 19 14:22 /dev/tty1 </pre> <p>Even weirder, this doesn't work:</p> <pre> root# cat </dev/tty1 bash: /dev/tty1: Permission denied </pre> <p>I am guessing this has something to do with the VM host, but both my VPS provider and I are out of ideas, and so is Google... Any clue as to why root cannot access a character device with root rw privileges?</p> <p>Update: I've made sure SELinux has been disabled; yet, the issue is still there....</p> <p>Update: The strace dump:</p> <pre> 32399 rt_sigaction(SIGTSTP, {SIG_DFL}, {SIG_DFL}, 8) = 0 32399 rt_sigaction(SIGTTIN, {SIG_DFL}, {SIG_IGN}, 8) = 0 32399 rt_sigaction(SIGTTOU, {SIG_DFL}, {SIG_IGN}, 8) = 0 32399 rt_sigaction(SIGINT, {SIG_IGN}, {SIG_IGN}, 8) = 0 32399 rt_sigaction(SIGQUIT, {SIG_IGN}, {SIG_IGN}, 8) = 0 32399 rt_sigaction(SIGCHLD, {SIG_DFL}, {0x807b990, [], SA_RESTORER, 0xb7e7b708}, 8) = 0 32399 open("/dev/tty1", O_RDONLY|O_LARGEFILE) = -1 EACCES (Permission denied) 32399 open("/dev/tty1", O_RDONLY|O_LARGEFILE) = -1 EACCES (Permission denied) 32399 fstat64(2, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 1), ...}) = 0 32399 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7fe1000 32399 write(2, "bash: /dev/tty1: Permission deni"..., 35) = 35 </pre> <p>Can't say it's making much sense to me... </p>
