[tor-relays] TOR relay and their flags

[androny]

Hello all!

My torrc main config:

SocksPort 0
RunAsDaemon 1
DataDirectory /tmp/.tor
ControlPort 9051
CookieAuthentication 1
ORPort 4999
AvoidDiskWrites 1
BridgeRelay 1
ExitPolicy reject *:*

so, its pure relay. Run arm and got:
"flags: none"

Well, read flags definitions at 
https://gitweb.torproject.org/torspec.git?a=blob_plain;hb=HEAD;f=dir-spec.txt 
and still don't understand it :-) My tor has almost 4 days uptime, and 
at logs have:

-----
Self-testing indicates your ORPort is reachable from the outside. 
Excellent. Publishing server descriptor
-----
Performing bandwidth self-test...done.
-----
Tor has successfully opened a circuit. Looks like client functionality 
is working
-----
Connections (1 inbound, 6 circuit, 1 control)
-----

It means, it works well - so, why my tor relay server doesn't have an 
"Running" flag, "Valid" flag or "Stable"?

Regards
And-ron
