Comment 37 for bug 363892

Hi Mark,

The following is from "man 5 modprobe.conf":

       Because the modprobe command can add or remove extra more than one mod‐
       ule, due to module dependencies, we need a method of specifying what
       options are to be used with those modules. /etc/modprobe.conf (or, if
       that does not exist, all files under the /etc/modprobe.d directory)
       specifies those options, as required.

So yes, all files under /etc/modprobe.d are treated as configuration files.
