Re: [PATCH v2 1/5] arm: mach-omap: Change mountpoint of boot partitions

Hi Daniel,

Your series wasn't forgotten. It's only that it took me some time to try
and implement links to directories. With this series I just sent and
"fs: Create automount entries for the default mount pathes" you should
be able to make this series a bit nicer. What I think of is that /boot
becomes a link to /mnt/mmcx.y or whatever provided /boot previously.

Could you give it a try?
