In Debian-Installer, a prebaseconfig script which runs shortly before the first reboot during the installation *should* actually install brltty into the target system and adjust the configuration file according to the settings passed as the boot prompt. However, this does not use debconf at all right now, so it is unrelated to my original question. > If current D-I is intended to install brltty automatically in new > system and the new brltty package is used in D-I, there might be some > difficulty especially for new users. As explained above, removal of debconf support would not affect the procedure during an accessible new system install using a braille display. It basically would only change things for people who install brltty onto an already running / installed system by invoking apt-get install brltty or some other equivalent command. > If the parameter given at the boot prompt of D-I is propagated to > brltty.conf of installed system, users don't need to edit brltty.conf > until they want to use the same system with the other braille > displays.

Yes, sort of, that is the only argument which still counts for debconf, however, I really am not sure if that alone warrants the maintainance nightmare that is a proper config-file parsing/changing debconf support code. Additionally, brltty 3.6 gained the ability to specify several different display types on different busses at the same time, which allows for quite flexible configurations. For instance, on my laptop, I like to use bluetooth as a bus to connect my braille star to the notebook, since I dont have to connect cables anymore. However, if for some reason I forgot my bluetooth adapter, I will need to be able to connect via USB, without having to change /etc/brltty.conf, because at that stage, I dont have any working display. So the ability to specify several display types on several busses makes this possible. Whenever there is no display connected, BRLTTY will try all of the specified combinations until it finds a display somewhere. As soon as that display gets disconnected, the whole circle starts over again. This is actually very handy, but it also means that if we want proper dialog based configuration via debconf, we (or better, I) have to implement multiple-device selection support in debconf. That doesnt exactly look like fun, and it only adds to the complexity, which would need fixup already anyway. -- CYa, Mario
