I made a /dev/urandom and a /dev/null after a chroot and it seems fine.
Which command create the /dev/* at boot?
Is there anyway to repair the installation now that I run (after a
chroot)?
If you are trying to do rescue in a change route, then what you want to do
is a bind mount. You'll probably also want /sys, /proc and maybe /run.
So for example if you were running a system from an initramfs or other kind
of rescue environment and the rootfs was on /dev/sda1, /boot was on /dev/sda2
and /home was on /dev/sda3 you might do the following:
mkdir /sysimage
mount /dev/sda1 /sysimage
mount -o bind /dev /sysimage/dev
mount -o bind /sys /sysimage/sys
mount -o bind /proc /sysimage/proc
mount -o bind /run /sysimage/run
mount /dev/sda2 /sysimage/boot
mount /dev/sda3 /sysimage/home
chroot /sysimage
At that point you should be able to run things like yum to repair the system.
You'll eventually want to relabel the system (once you have it working again).
You can touch /.autorelabel (in the chroot) to flag this to happen at the
next boot.
