Yea, i thought of that, but whasnt sure how to implement that with
existing dbootstrap routines (i didnt look too hard though)

Cool, sounds like having a seperate routine would be good then.
The general filesystem browser is basically all there in tzconfig.c,
tzconfig would be simplified heaps.

functions that would be "poached" into the filebrowser would be
configure_timezone_step1 from tzconfig.c, this has to be modified as its
hardcoded to call  write_timezone which is where it uses the selected
read_directory from tzconfig.c this wouldnt have to be changed at all.

No, i wasnt doing anything fancy, i was thinking fairly superficially,
if you needed to install to a block device that dbootstrap doesnt
otherwise recognise (e.g md? ) then you could go to the console prepare
the device (for raid, make an //etc/raidtab and run mkraid) then select
it manually as an install target. 
Im not totally sure about how loop devices, so maybe work would be
required for that... dunno.
I didnt think of looking through /proc.

I didnt even think of looking around /proc for the block devices.
