Description Peter Müller 2020-06-09 18:49:09 UTC 
> Uprobes is the user-space counterpart to kprobes: they enable instrumentation
> applications (such as 'perf probe') to establish unintrusive probes in

> probes are hit by user-space applications.

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