I'm working on a change for Fedora openQA to run a command that can be very long from a serial console. It seems when a command is very long and you run it from a serial console, the testapi::wait_serial($cmd . $marker, no_regex => 1, quiet => $args{quiet}); call that happens in the middle of script_run (the distribution.pm one) on serial consoles fails because part of the command is lost. This is the failure I get:

note how the 'result' is the last 4096 characters of the 5404-character string, so there seems to be a 4096 character limit we're running into somewhere in here.

I can probably work around this by having the test write the build list to a file in smaller chunks and then having the script read it in from the file, or something like that, but it's a bit of a pain. I want to run this command from a serial console precisely because it's very long, and typing it into a regular console takes a long time (and is obviously subject to potential typing errors).
