The alfred server always needs interfaces to operate on. But these interfaces might not exist at the moment when the daemon process is started. This situation stopped the startup process after the init scripts waited for a longer period of polling the system state. But alfred is able to deal with interfaces which disappeared at runtime but existed at startup. To force a similar behavior for the alfred startup, the parameter "--force" or "-f" is used. The extra polling code is therefore no longer needed in the init scripts. Signed-off-by: Sven Eckelmann <sven@narfation.org>

Subject: alfred: Save global mode flags in bitfield
|
|
|
|
The verbose and ipv4mode entries in the globals structure is only used to
|
|
save a boolean information. So just use a bit in a bitfield to store this
|
|
information instead of a full int.
