I have an ubuntu linux image, which I use for my single board computer.
When I write it the media (it's an sdcard), then boot and log in, it asks me to change the password.
Since I can mount and modify the sdcard content with another computer before actually performing the boot, I'd like to disable the password expiry.
I know that on a running system I can use
chage, but in this case, the target system is on the card.
Is it possible to do it?
