As usual, files are all sorted lexically by filename not by path, and
are read in order.

Files in /etc with the same name in /lib completely overwrite files in
/lib, but only files with the same name, all other files are still
read from /lib.

Packages should drop files in /lib, _never_ in /etc. /etc is reserved
for local administration only. The 'admin-overwrites' in /etc can
overwrite/disable individual files in /lib.
