[Buildroot] [PATCH 1/1] iso9660: Added support for overlay directories

[Martin Bark]

This patch adds a variable BR2_TARGET_ROOTFS_ISO9660_OVERLAY that
is similar to BR2_ROOTFS_OVERLAY except the files are placed in the
iso9660 file system.

 I haven't tried it but it looks obviously-correct.

 Jean Sergemoel has a patch in the queue that does a similar thing (in
addition to a few more changes). Jean, could you rebase your patches on
top of this one? And, if possible, also test if this one works for you.
If yes, add your Tested-by to this patch.

 Regards,
 Arnout

Since Buildroot only builds root filesystems for the target device,
it would probably be safe to drop the "TARGET_" distinction from
that variable name.

 Agreed, but that should not be done in this patch. All the rootfs stuff
is currently using the BR2_TARGET_ROOTFS_ prefix, so this patch should
stick with that convention.

Arnout,

Thanks for the review.  Yes by some strange coincidence both Jean and 
myself sent patches for the iso9660 file system on the same day.  I 
agree it would be best to rebase Jeans patches.


Jean,

Let me know if you want any assistance on producing an updated patch set.

Thanks

Hi All,

Ok, I will include that in my patch.

Hi All,

I will send new patch to include your remark.
I use my real name (Jerome Sagnole) :)

Arnout, for your remark on default (option 
BR2_TARGET_ROOTFS_ISO9660_ROCK_RIDGE)
I keep this default for compatibility because this option is activate in 
old code. If you want I can suppress that.

Regards,
Jerome
