Acpid: Better document the events/anything file

In the Power Management section, acpid and elogind are both mentioned, along with the incompatibility between them. However, the only documented "solution" is to completely disable acpid (which breaks things like acpi_listen) or completely remove acpi handling from elogind (which break proper sleep/etc handling in DEs which use it).

In reality, commenting out or removing /etc/acpi/events/anything is enough to disable the handlers on the acpid side. This is a 3rd option, and the only one of these that works when both elogind's handling is needed by a DE and the acpid socket (or custom handlers) are required. Perhaps this could be mentioned as a solution when disabling acpid or elogin's handlers is not possible.

Trova la sezione «Power Management» nella documentazione di Void Linux e verifica la spiegazione relativa ad acpid ed elogind. Documenta il commentare o rimuovere /etc/acpi/events/anything come opzione aggiuntiva e verifica che la sezione spieghi quando ciò preserva sia la gestione di elogind sia l’accesso di acpid al socket o ai gestori personalizzati.
