If root filesystem is multidev btrfs, do not attempt to pass all devices as kernel root= argument. This results in splitting command line in GRUB due to embedded newline and even if we managed to quote it, kernel does not know how to interpret it anyway. Multidev btrfs requires user space device scanning, so passing single device would not work too. This still respects user settings GRUB_DISABLE_LINUX_UUID. Not sure what we should do in this case.

This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
