# ------

# generic.
#
# for the disc and cd ones, if there is a a matching /dev/hdX symlink and
# hdX_args is set in the config file, use hdX_args. otherwise, if there is a
# matching /dev/discs/discX or /dev/cdroms/cdromX symlink, and discX_args or
# cdromX_args is set in the config file, use discX_args / cdromX_args. finally,
# if all_args is set in the config file, use that.
#
# for the generic ones, sort them and look for genericX_args in the config file
# or use all_args.
#
# if /dev/ide does not exist, check the /dev/hdX entries, and see which ones
# correspond to real devices by opening them for reading. then check hdX_args
# and all_args in the config file.
#
# for each device considered, if no args are found in the config file, do not
# run hdparm.
