mknod at linux startup

Question

I have a device which I added to /etc/modules, previously it was added by insmod then mknod..

I want to add mknod command at kernel boot..

  # load driver
/sbin/insmod -f ./${module}.${suf} $* o_dbg=1 || exit 1

# Get driver major number
major=`awk "\\$2==\"$module\" {print \\$1}" /proc/devices`

mknod /dev/${device}0 c $major 0

1- I added the module to /lib/modules/uname -r/

2- debmod -a

but I don't know how to make mknod automatically

If your system is having udev or mdev then you can write rules to create device nodes automatically. Otherwise, you can manually call sys_mknod from your module code. Make sure that sys_mknod is exported.
