2010-06-09 04:44:44 Populating /dev with mdev

Hi, friends...

I can see a SATA drive in /sys/block directory (sda, sda1, sda2).

Then I try to populate it into /dev with a command mdev -s.

As a result, I get needed devices (sda, sda1, sda2).

But, they are created as character devices.

crwxrwxrwx ... 8, 0 ... /dev/sda

crw-rw---- ... 8, 1 ... /dev/sda1

crw-rw---- ... 8, 2 ... /dev/sda2

My mdev.conf is very simple:

sd* root:root 0777

Is it a wrong kernel configuration or may be I didn't do something important

with busybox?

Thank you in advance for any suggestion...

you didnt say what version of software you're using

make sure you've enabled the deprecated sysfs options in your kernel

The problem was with my current version of busybox (1.10.2). I didn't change it and just corrected the .config.

Switching off the option "Support /etc/mdev.conf" (MDEV_CONF) solves the problem.

Thank you for cooperation...
