Description linuxcbon 2015-05-06 22:14:07 UTC 
Kernel 3.19.2

inittab 
::sysinit:/etc/rc.d/rc.sysinit
tty1::respawn:/sbin/getty 38400 tty1
tty2::respawn:/sbin/getty 38400 tty2
::ctrlaltdel:/sbin/reboot

/etc/rc.d/rc.sysinit
#!/bin/busybox ash
busybox mount -t devtmpfs dev /dev

At bootup /dev is empty. After the kernel is loaded I get this :
mount: mounting dev on /dev failed: device or resource busy
But /dev was created normally :
drwxr-xr-x  2 root root       60 May  6 23:39 bsg
drwxr-xr-x  3 root root       60 May  6 23:39 bus
crw-------  1 root root   5,   1 May  6 23:40 console
......

dmesg
