More details in the "mtype" field of mdb

[Antoine Pietri]

Currently the "mtype" field of mdb contains 3 values: user, orga and server. This is not really practical, because you can't pssh to all the netbooted machines with --mtype=orga, it also tries to pssh on external devices (laptops, phones, ...) We should first change the values of this field with:

• netboot/internal/..? for the machines we need to boot using netboot and a rhfs
• external/..? for the external devices (laptops, phones, ...)
• server for the server

We could then add a special field utype for the firewall:

• contestant for the contestants
• orga for the organizers
• service for the servers

[Antoine Pietri]

The main difference we want is actually managed and unmanaged since we can't really firewall the external devices. Maybe we could just remove the server and services fields. Is utype that important? Maybe to prevent contestants to log on to organizers machines?

[Rémi Audebert]

utype enables us to select the machines to run commands. For example we only restart kdm on the users machines and leave the orga working. The field is useful, it should stay.

[Antoine Pietri]

Shouldn't we already know that from presenced?

[Rémi Audebert]

Both - current user with presenced and statically defined machine purpose on mdb - are useful. For example we can conflose all the contestant machines but keep the organizer one alone, even if nobody is currently logged in those.
