22 Or, actually, you could just give in and use a different dhcp
23 client... one more forgiving of less RFC compliant servers. Just
24 winging an admittedly untested idea... try "busybox udhcpc" and see if
25 it gives you the right IP... and if so, try emerging net-misc/udhcp
26 (different from BB's built in, but it's worked in all the same places
27 as BB's has for me, which includes some very cheap routers) and
28 setting your conf.d/net to use it over other clients. ( modules=(
29 "udhcpc" ) )
