[PATCH kmod v2 07/17] man: depmod.d: document the config file order handling

[Emil Velikov via B4 Relay <devnull+emil.l.velikov.gmail.com@kernel.org>]

From: Emil Velikov <emil.l.velikov@gmail.com>

The depmod.d configuration order/handling aligns with existing tools
such as sysctl.d, even though there is no mention in the manual.

Reorder the list in SYNOPSIS and add a bit of verbiage describing things.

Section is inspired by sysctl.d(5) and sysctl(8).

+# CONFIGURATION DIRECTORIES AND PRECEDENCE
+
+Configuration files are read from directories in listed in SYNOPSYS in that
+order of precedence. Once a file of a given filename is loaded, any file of the
+same name in subsequent directories is ignored.
+
+All configuration files are sorted in lexicographic order, regardless of the
+directory they reside in. Configuration files can either be completely replaced
+(by having a new configuration file with the same name in a directory of higher
+priority) or partially replaced (by having a configuration file that is ordered
+later).
