When using WPA/DHCP the DHCP is obtained in background (see network.sh/wpa_action.sh). The problem is that my following init-scripts fails because it takes one or two seconds to get the lease (until the lease is obtained name resolution is not working).
I did temporarily fix the problem by inserting (right after network.sh) a self written script that will sleep some seconds.
Go to SliTaz Labs, register there (requires email confirmation), sign in and go to the project you want to (boot scripts?) and then check events for that project, it should have Bugs in it. There you can add new event (i.e. bug report). Just learned this last night:). Hope this helps
