# Map Caps Lock to Control
# I copied from /lib/udev/hwdb.d/60-keyboard.hwdb
# Used to be
# evdev:atkbd:dmi:bvn*:bvr*:bd*:svnDell*:pnXPS*:pvr*
# KEYBOARD_KEY_8c=!unknown
evdev:atkbd:dmi:bvn*:bvr*:bd*:svn*:pn*:pvr*
KEYBOARD_KEY_3a=leftctrl
そして
$ sudo systemd-hwdb update
/etc/udev/hwdb.d/my-custom.hwdb:19: Property expected, ignoring record with no properties
$ sudo udevadm trigger /dev/input/event0
でもうまくいきません。
単純なことだと思うのですが、今はかなり目が回ります。

$ udevadm info -a -p $(udevadm info -q path -n /dev/input/by-path/platform-i8042-serio-0-event-kbd )
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
