colored prompt in early userspace

hi, when you add the `break` parameter to the list of parameters passed when the system boots, you find yourself in an interactive shell that allows you to issue commands, perform tests, and so on... the shell is apparently provided by `ash`. how to have a colored prompt (which visually helps to detach the prompt from the rest) ? the `~/.profile` file mentioned here and there does not seem to be read/used. `/.profile` and `/etc/profile` don't do much better. `ashrc` also tested without success. if the prompt offered at this level can be colored, I think it would not be a luxury to implement it directly in mkinitcpio ;-) regards, lacsaP.
