Consider the following configuration: * gentoo linux with openrc, /usr is placed on separate partition * removable wireless card (connected by usb in my case), configured to use wpa_supplicant (by corresponding entry in /etc/conf.d/net). It may be present during system boot, or may be plugged in later, so net.wlan0 is allowed to be hotplugged. When wireless card is plugged in before system boot, it is "hotplugged" by init system very early (before local filesystems are mounted); the corresponding init.d script is started at the same time. Because /usr is not mounted, network init script is unable to find wpa_supplicant binaries, so it refuses to load wpa_supplicant network module. As a result, when net.wlan0 is actually started, it is configured without wpa_supplicant (even if /usr is already mounted at that moment). Possible workaround is to create on root filesystem symlinks /usr/bin/wpa_cli and /usr/sbin/wpa_supplicant pointing to some binary on root filesystem (for example, /bin/true), and add rc_need_wlan0="localmount" to /etc/conf.d/net. But correct solution (I suppose) is to load network rc modules after localmount. Reproducible: Always
(In reply to comment #0) > correct solution (I suppose) is to load network rc modules after localmount. If your /usr isn't available and you have needed stuff there, you shouldn't have enabled hotplugging it in the first place. :) rc_hotplug="!net.wlan0" in /etc/rc.conf (or rc_need_wlan0="localmount" as you've already noted.) Why would you load networking stuff after localmount when all normal network stuff resides in /

This doesn't solve problem with initialization during system boot: network modules (those in /lib/rc/net) are scanned when net.wlan0 init script is started; but it is started early, BEFORE localmount - even if we specify rc_need_* - in this case, it just waits until localmount is started, then executes start() function; but network modules are scanned immediately after script is executed. > Why would you load networking stuff after localmount when all normal network > stuff resides in / I suppose, wpa_supplicant is considered "abnormal network stuff" :) It can't be easily relocated to / because it depends on libraries normally installed into /usr. Perhaps more correct solution is to add to /etc/conf.d/net ability to force usage of network module (even if required binary is not found). Together with rc_need_* it would solve my problem...

Yeah, so it waits until the needed stuff is available and starts then... and the problem with this is where? Sound like it works exactly like it should. Maybe you should describe your problem with this in more detail?
net.foo already has a need dependency. I don't see a problem here.

If you can still produce this with 0.6.1-r1 please reopen. As Roy has already stated the localmount depend is already there which makes this invalid as far as I see.
