It would be nice if both the FireWire and USB subsystems started up sooner. T= here are other issues (with USB for instance), where ukbd not being initiali= zed before the mount root prompt can leave the system undebuggable. In the short term: can the SYSINIT priority be changed in the drivers to sup= port this? It would be nice if there was a pluggable infrastructure for bootloader enab= ling of devices as debugger consoles that would make this possible. Thanks! -Garrett=
