Persistent Custom Files

When an expert user needs to modify some configuration with custom settings
(e.g., complex firewall rules) or wants to add new tools to the "official" firmware,
he can use the custom mount directories mechanisms: This allow to store per-
sistent files by placing them into the second ext4 partition on the SD drive moun-
ted as /media/data which will be then mounted at next boot into the operating
system directories:

Description
The device was pre-
viously in a HO exit
state but and enter
the holdover time
source until it has
finally expired. Even if
we will still be con-
nected internally to
the HO clock, we
announce ourself
exactly like FR and we
allow to reset the
algorithm
The last mode that
was "ready" has been
exited in HO mode.
The only thing that we
perform here is
increasing our clock
accuracy and stay in
this mode until the
timer expired
The Holdover timing
source is learning in
background from the
active timing source.
If triggered, it will dir-
ectly reach its expired
state.
