// so if we want them to work as expected we need to mount the persistent dir and the bind dir that will
// then end up in the system as /usr/lib/extensions is not valid anymore
// So after the install from livecd we need to:
// - mount persistent in /usr/local
// - create the dir that will be binded into /var/lib/extensions after reboot in /usr/local/.state/var-lib-extensions.bind
// - rsync whatever is in the /var/lib/extensions to /usr/local/.state/var-lib-extensions.bind so we dont lost thing shipped with the install media
// - bind the dir so the extension gets persistent after reboots
// - umount the bind dir
// Note that the binding of /usr/local/.state/var-lib-extensions.bind to /var/lib/extensions on active/passive its done by inmmucore based on the
// 00_rootfs.yaml config which sets the bind and ephemeral paths.
