Subject: [PATCH] gluon-core: preserve explicitly marked network and system
sections
A section can be marked as preseved by setting the gluon_preserve option
to 1. In addition the following conditions must hold:
- The preserved section must not already exist after OpenWrt's and
Gluons setup scripts run. Modifying existing sections is currently
unsupported.
- Preserved sections must be named, so it can be detected whether a
section conflicts with a preexisting one.
