Description:

Some network interfaces need not be waited for, but might take long to establish. For instance, when setting up a home server, the ADSL connection is not vital and can be established in the background. But you cannot start @net-profiles in the background, since you need to be 100% sure that all your LAN connections are up before starting DHCP or radvd.

It would be nice to have this in /etc/rc.conf (with support in /etc/rc.d/net-profiles):

NETWORKS=(@adsl @sometunnel lan1 lan2 wifi)

Current package version: netcfg 2.5.4-1
This task depends upon

Reason for closing:  Implemented
Additional comments about closing:  Do note that the user has to take care to only background profiles on unique interfaces, or race conditions could occur.

This is not very hard to implement, but could introduce a possible race condition when multiple profiles try to use the same interface. We could document this and require the user to make sure all backgrounded network profiles use interfaces not used by any other connected or connecting profile.
