file_is_not_sym() currently only checks for xen-syms. Extend it to disregard xenpolicy (XSM policy files) and files ending .config (which are built by the Xen upstream build system in some configurations and can therefore end up in /boot). Rename the function accordingly, to file_is_not_xen_garbage(). Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com> Reviewed-by: Daniel Kiper <daniel.kiper@oracle.com>
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.
