Re: a blindunfriendly Sarge installer problem


Sorry to have been postponing this for quite a long time.

The current .udeb holds a ~175Ko binary. Version 3.7 might be bigger
since some drivers were added.

It seems so, indeed: it holds a /usr/lib/prebaseconfig.d/50brltty that
grabs parameters from the kernel command line (just like Aldo asked
for), and prepares a /etc/brltty.conf. Then /etc/rcS.d/S02brltty gets
launched and starts brltty as appropriate.

With USB devices and recent brltty versions, there should even be no
need for any parameter, since autodetection is safe in such case.

Another solution for parameter passing could be pre-seeding, just like
other automatic installation parameters. The only important thing
is that it needs to be done _before_ the user has to read or type

Note: Mario Lang is still the maintainer for the brltty package, the sad
thing is that he doesn't seem to have much time to spend on it.
