    enable sysrq + add special sysrq debugging when stuck on plymouth · 4eec6b8d

    this is special error handling.
    we have persistent problems that reboots get stuck. previous debugging
    attempts via journald didn't give useful results because according to the
    journal the system is shutting down as expected. It's clearly stuck on
    something though.
    so... to debug this we'll try to get as much out of the kernel as possible
    and then crash the system for good measure.
    additionally we'll now enable sysrq all the time since ubuntu's default
    security would disable most of the debugging commands. since we have no
    tests relying on the security being present we may as well just disable it
