I had a similar experience with the Format HDD prompt. I think it may possibly be linked to a minor problem with the mdev script which af123 knows about already. Yes, exact details of what each package contains would be good. For instance , I noticed that the Network utilities package duplicates the ifconfig, route, and hostname commands which already exist in the busybox binary. The custom firmware has only modded the publicly licensed linux busybox OS. I believe the firmware version is coded somewhere in the Humax binaries, and so would not be quite so easy to change.
