 Hi all!

 I'm using xen on gentoo with grub2 and seems there is and issue with 
 default xen detection mechanism because it also adds menu entries for 
 all xen symlinks in boot and for xen-syms [see grub.cfg.unpatched] that 
 shouldn't happen. Contents of my boot directory is

 x201 ~ # ls -l /boot
 total 30020
 -rw-r--r-- 1 root root  2549447 Apr  2 18:03

 lrwxrwxrwx 1 root root       12 Mar 26 03:34 xen.gz -> xen-4.1.0.gz

 With patch for 20_linux_xen [see grub2-xen.patch] i get sane menu 
 entries [see grub.cfg.patched]

Just for record: this patch wasn't accepted because it's not 
POSIX-compatible. Please fix this.
