This issue has been discussed here : http://lists.openembedded.org/pipermail/

Reverting this patch to solve the alternative problem cannot be a definitive 
solution as it breaks boot on some boards. IMHO, I'd rather break the 
alternative system than boot (full disclosure : I use opkg's update-
alternatives).

As already said, absolute paths cannot be used in bootloaders since it may 
point to an invalid location (rootfs may not be mounted). I do not have 
another solution with plain 'ls', but I think we should find a way to better 
handle all cases than going back and forth on this patch.

FYI, this is my use case : I have a bootloader which resides in EEPROM, but 
needs to boot kernels that can be upgraded. Therefore, I rely on a fixed path 
to the last kernel / devicetree on a specific partition outside rootfs.
