Hi folks,

On creating a loop block device, run;

mknod /dev/loop0 b 7 0
mknod /dev/loop1 b 7 1

7 and 0/1 are major and minor number respectively. What does it mean major/minor?

Wlhere can I find the latest version of The Linux Bootdisk Howto? The version I have is;

Major generally points you to a device driver, the minor numbers allow that driver to address individual devices. For instance, on my system my tty devices are major 4, and each tty has its own minor number. Think of it as an apartment block - you have a (major) building address and each apartment has its own (minor) number.

Hi scm,

Tks for your explanation. How to find the major/device driver number e.g. block, tty devices, etc.
