Nope, didn't work. I edited the current entry, reran grub2-mkconfig
etc. and dracut.  I checked the entries and they are regenerated from
somewhere with the changes reverted, so the question is where?

A logical place to look is in /etc/dracut.d. The manpage for
dracut.cmdline says you can specify a "root=UUID=..." parameter, but
not where you put it ('dracut root=...' and 'dracut --root=...' both
fail). The manpage for dracut.conf has no mention of a root parameter,
and the contents of /etc/default/cmdline come in part from the files in
/etc/dracut.d (that's where my 'resume' parameter comes from).
