Improve grub-mkconfig performance when there are several menu entries on a single filesystem. * util/grub.d/10_linux.in (linux_entry): Cache the output of prepare_grub_to_access_device. * util/grub.d/10_kfreebsd.in (kfreebsd_entry): Likewise. * util/grub.d/30_os-prober.in: Likewise.
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.
