chrooting and device permissions


I'm currently trying to chroot an apache server on my system (RedHat EL5) with mod_perl and mod_ssl , but i encounter some difficulties. I have permissions problem with /dev/null /dev/random /dev/urandom.

To debug my chrooted apache, i'm using strace.

When i'm creating a node "null" (mknod null c 1 3) using mknode in my chrooted /dev/
I obtain the following error when running strace with my chrooted apache

open("/dev/null", O_RDONLY|O_LARGEFILE) = -1 EACCES (Permission denied)

but when i removed it and make "touch null"

i don't have any problem.

I chmoded the node to 777 and changed his owner, but i have the same error.

I set SELinux to disabled in /etc/sysconfig/selinux

Any ideas ?

Is your chrooted system on an FS mounted with nodev?
