Description: Now qemu package depends on brltty, which depends on cython, so it's pull about 130MB of unneeded packages. I'm tried a bit to make .so stub and qemu works fine. Seems like brltty is completely unneded dependence.

Additional info:
* qemu=2.6.0-3

You can make stub with this command:
echo "brlapi_acceptKeyRanges brlapi__acceptKeyRanges brlapi_acceptKeys brlapi__acceptKeys brlapi_closeConnection brlapi__closeConnection brlapi_defaultExceptionHandler br

It is also easy to compile it without, either by passing --disable-brlapi, like qemu-headless, or by compiling it on a system that does not have brltty in the first place. While I do understand that there are disabled users which can benefit from this, the majority of packages is not this accessible, and they are perhaps better served by a specialized spin of the distribution. In any case, 130MB of dependencies for a feature that only a vast minority of users can benefit from is excessive.

A second gratuitous dep is xfsprogs, which should be optional.

I've given to building my own qemu without brltty and xfsprogs. It would be nice if dependencies were trimmed back to the previous set.

I totally agree with topic starter, it would be nice to make brltty optional if that's possible.

I have a request to set pulseaudio optionally, if possible.
Has been set as required dependency in qemu 2.11.0 (test repository)

Since  FS#52603  brltty doesn't pull in python/cython automatically. Installing brltty on top of base/base-devel/qemu in a chroot is:

But most of that is things like libx11 and icu, which will likely be installed for other reasons as well. I don't know whether that qualifies as a reason to bring back brltty but it is something to think about.

hello. as blind arch and qemu user I can say: I agree with the Eli's arguments.
also as TalkingArch maintainer and archlinux accessibility enthusiast I am sure that you should use every opportunity to improve the accessibility of programs. especially when this support is already working and helps VI persons.

In conclusion, I want to ask you to enable brlapi support in qemu.

Restored brltty in qemu 4.2.0-2
