Previously, the generation number was only increased for successful evolutions. This led to a confusing state in /run/net where multiple <N>-ABANDONED-<date> directories could exist, with the same value of N. Move to a scheme where the generation increments every time we evolve, even if the evolution fails. If multiple consecutive evolutions fail, we can now unabiguously determine the order in which they were executed.
Configuration Daemon
confd is the Infix configuration daemon that serves as the glue
between sysrepo and netopeer2 (NETCONF) and the UNIX system under
it all.
Factory & Failure Config
Infix supports both static and dynamically generated factory-config. At
boot the dynamic is always generated to /run/confd/factory-config.gen,
which is installed to /etc/factory-config.cfg and used by default, if
that file does not already exist. The same applies to the failure mode
configuration.
The following describes how a vendor/product specific config is found
and installed into /etc/factory-config.cfg before the dynamic one is
installed.
/etc/factory-config.cfg: built into the image, e.g., r2s/usr/share/product/<PRODUCT>/etc/factory-config.cfg, where the<PRODUCT>is determined from the VPD, which is available afterprobehas run, in/run/system.jsonas"product-name". The lower case version of the string is used
In the second option a script running just after probe will in fact
cp the complete product specific directory to /, meaning any file
and directory that is writable at runtime can be overloaded with device
specific versions.
