So I got this [Chromebook][chromebook-post] in Developer Mode and wanted to set
|
|
|
|
|
a root password to atleast protect it a little.
|
|
|
|
|
|
|
|
|
|
Easy:
|
|
|
|
|
|
|
|
|
|
~~~bash
|
|
|
|
|
sudo chromeos-setdevpasswd
|
|
|
|
|
~~~
|
|
|
|
|
|
|
|
|
|
Oh, wait. You pressed enter twice here? Backup your data and reset the device.
|
|
|
|
|
|
|
|
|
|
This is what `chromeos-setdevpasswd` does:
|
|
|
|
|
|
|
|
|
|
~~~bash
|
|
|
|
|
#!/bin/sh
|
|
|
|
|
|
|
|
|
|
mkdir -p /mnt/stateful_partition/etc
|
|
|
|
|
echo "chronos:$(openssl passwd -1)" > /mnt/stateful_partition/etc/devmode.passwd
|
|
|
|
|
~~~
|
|
|
|
|
|
|
|
|
|
openssl does not care that you just used an empty password, atleast if you also verify it.
|
|
|
|
|
But so do `su` and `sudo`, which means you won't be able to get root rights again.
|
|
|
|
|
|
|
|
|
|
But it's Chrome OS after all, so most things are stored in your Google profile
|
|
|
|
|
anyway, resetting and restoring the thing is done easily.
