Foreman 0.4.0

If we go to a host and try and edit or delete the root password then the yaml seems to end up
with something bizarre in it.

root_pw: $1$foreman$mScJrIfRylirlhmRGTArV0

We did not add a $foreman in our password string, in the case below the password was entered as 'abc'.

Attached screenshot shows where we are changing the root password for the kickstart file.

Here is the log entry:

And finally a related question. Are we meant to adding the root password or the crypt of the password
in this box.
