 We could check for /proc/acpi/event before starting acpid, but as it's
 possible to override this pathname with acpid's -e flag, it would be
 hard to check whether the flag was passed or not.

 I can't really come up for a good reason to override this path; I don't
 think anybody has proc somewhere else, the relative /proc pathname is
 probably hardcoded in the kernel, so the only use case I can imagine
 would be some kind of event relay file.

 What do others think of testing for /proc/acpi/event (instead of
 /proc/acpi) at the top of acpid.init and exiting immediately with 0 if
 not present? (disabling acpid)
