Well, it's taken a few hours, but I have it working. Just a few wrinkles to clear up: 1. dracut: 90crypt: Could not find any command of '/lib/systemd/systemd- cryptsetup cryptsetup'! ...and similar for bluetooth. What do I have to include in /etc/dracut.conf.d/mine.conf to silence these? I already omit the relevant modules: $ grep -e crypt -e blue /etc/dracut.conf.d/mine.conf omit_dracutmodules+=" bluetoothd " omit_dracutmodules+=" systemd-cryptsetup " omit_dracutmodules+=" cryptsetup " 2. dracut: No KEYMAP configured. $ grep i18n /etc/dracut.conf.d/mine.conf i18n_vars="/etc/conf.d/keymaps:KEYMAP /etc/conf.d/keymaps:WINDOWKEYS / etc/conf.d/consolefont:FONT" Notice that only KEYMAP is complained about. The FONT in consolefont points to /usr as well as KEYMAP. -- Regards, Peter.
