[zehnm]

Description

After introducing the read-only root file system, custom certificates keys can no longer be copied to the device.

Custom certificates, for example self signed certificates of a home automation server, can be installed on the remote. Either with the official system tools, or through other means.

Your Environment

• Version used: 2.0.0-rc2
• Running on:
  • YIO Remote

Additional context

Certificates are located in:

• /etc/ssl/certs/
• /usr/share/ca-certificates/mozilla/
