Lennart argued that /dev/hd* is caused by using the deprecated
CONFIG_IDE in the kernel and therefore rejected adding "hd*" to upstream
udev.
CONFIG_IDE seems to come from common-pc-drivers.cfg [1] but that's just
a guess - I'm not entirely sure how to identify the actual kernel config
fragments that were used during a build. Anyway, it has been there since
2011 and modernizing that is a different topic, so I'll just send the
patch for systemd/udev.
