Create Linux Users on mounted disk image

Hi Everyone,

I'm currently in the middle of developing an automatic system which can provision Linux VMs automatically.

Let's say I have a disk image which has a Linux distro installed on it. How would I change the root password on that, without having to boot the OS?

It would be nice if I could just simply run passwd with some switch to point to the /etc/shadow file on the (mounted) VM disk image..

Any help would be appreciated

Thanks

Hi jonnytabpni,

You can use chroot for that.

Ex:

your image is mounted in /mnt/myImage

Code:

chroot /mnt/myImage
passwd root
exit

That should do the trick.
