Quoted from #12433:
> Uprobes is the user-space counterpart to kprobes: they enable instrumentation
> applications (such as 'perf probe') to establish unintrusive probes in
> user-space binaries and libraries, by executing handler functions when the
> probes are hit by user-space applications.
>
> ( These probes come in the form of single-byte breakpoints, managed by the
> kernel and kept transparent to the probed application. )

IMHO this can be safely disabled, as there is little if any need to debug
userspace programs _that_ deeply on an IPFire machine.

Fixes: #12433
