When generating grub.cfg using grub-mkconfig and the scripts 10_linux and 20_linux_xen there is no way to add kernel command line parameters _only_ to the recovery entries generated. This is needed to e.g. start a debug shell in installations using systemd using the kernel command line parameter "systemd.debug-shell" or to recover in a system with encrypted root in situations where the decryption of the root filesystem per crypttab in the intiramfs image is broken and the recovery entry should contain information how to decrypt the rootfs (cryptopts=). This patch does not change the default behaviour of the GRUB if GRUB_CMDLINE_LINUX_RECOVERY is not set. If GRUB_CMDLINE_LINUX_RECOVERY is set and the generated recovery entry should include the kernel parameter "single" the parameter must be explicitly included in GRUB_CMDLINE_LINUX_RECOVERY. As far as I know all credits for the idea and the initial implementation go to Kyle Ranking of Purism.

All executable files in this directory are processed in shell expansion order. 00_*: Reserved for 00_header. 10_*: Native boot entries. 20_*: Third party apps (e.g. memtest86+). The number namespace in-between is configurable by system installer and/or administrator. For example, you can add an entry to boot another OS as 01_otheros, 11_otheros, etc, depending on the position you want it to occupy in the menu; and then adjust the default setting via /etc/default/grub.
