Subject: linux-yocto 4.4: enable overlayfs
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fheads%2Frbt%2Flinux;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

linux-yocto 4.4: enable overlayfs

So that iso can work well, otherwise the iso is readonly and there would
be errors. The other way is aufs, but overlayfs is more pupolar and had
been merged by kernel mainline.
