We recently made sure that after doing a snap refresh, the rich mode
(i.e., either rich or basic) is preserved. This was implemented by
storing the rich mode in a state file. When the client starts, it loads
the rich mode from said state file if it exists.
Unfortunately, on s390x, it causes installs to default to basic mode.
This happens because on this architecture, a subiquity install consists
of:
* a first client (over serial) showing the SSH password
* a second client (logging over SSH) actually going through the
installation UI.
Since the first client uses a serial connection, the state file is
created with rich-mode set to basic. Upon connecting using SSH, the
state file is read and the rich-mode is set to basic as well.
Fixed by storing the rich-mode in two separate files, one for clients
over serial and one for other clients.
