# symlinks") those symlink aren't distributed in linux-firmware but are created
# automatically by its copy-firmware.sh script during the installation, which
# parses the WHENCE file where symlinks are described. We follow the same logic
# here, adding symlink only for firmwares installed in the target directory.
#
# For testing the presence of firmwares in the target directory we first make
# sure we canonicalize the pointed-to file, to cover the symlinks of the form
# a/foo -> ../b/foo  where a/ (the directory where to put the symlink) does
