[Debian-on-mobile-maintainers] Bug#1017842: osk-sdl: keyscript remain running in some circumstances

[Balint Kovacs]

Package: osk-sdl
Version: 0.67-2
Severity: important
X-Debbugs-Cc: dratini0 at gmail.com

Dear Maintainer,

I have osk-sdl installed on a Pinephone and a Steam Deck (customized with
Debian). After upgrading to 0.67-2, and rebooting my either device, I have
noticed that both get stuck after entering my passphrase into osk-sdl. They are
both configured to use the keyscript. Adding set +x to the top of the
keyscript, it revealed that it was the cat > /dev/null line that was never
returning. Commenting out this line fixed the issue on both of my devices.

An interesting addition is the fact that if I added break=mount or
break=mountroot to my kernel command line, and then exited the shell that came
out, the issue didn't happen, but if I used break=premount, it did. However,
this was only tested on the Steam Deck.

I use the same passphrase on both systems, which is between 20 and 30
characters long. On the Deck I was using a USB keyboard, on the PP I was using
the touchscreen or the keyboard case.
