[solved] Reset root password of factory os

[pm4888]

Please give some suggestion/hint here. I have alarm working on my pogoplug e02 on a USB ext hdd. If I reboot without the usb hdd it boots into original factory os. However I forget the root password and would like to leverage existing alarm to reset it. I search the forum and internet a bit and they all seem to mention mounting /dev/mdtblock? device, which doesn't seem to exist. What's the trick here?

Thank you.

$this->bbcode_second_pass_quote('', '[')root@pogoplug ~]# ls /dev/mtd*
/dev/mtd0 /dev/mtd1 /dev/mtd2 /dev/mtd3
/dev/mtd0ro /dev/mtd1ro /dev/mtd2ro /dev/mtd3ro
[root@pogoplug ~]# mtdinfo

[root@pogoplug ~]# mount -r -t jffs2 /dev/mtd2 /mnt
mount: /dev/mtd2 is not a block device
[root@pogoplug ~]# cat /proc/mtd

it seems to be working by manually creating the devices:

$this->bbcode_second_pass_quote('', 'c')d /dev/
mknod mtdblock0 b 31 0
mknod mtdblock1 b 31 1
mknod mtdblock2 b 31 2
mknod mtdblock3 b 31 3
mknod mtdblock4 b 31 4
mknod mtdblock5 b 31 5
mount -t jffs2 /dev/mtdblock2 /mnt
