Subject: d1: enable overlay support
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1e7950a45de593354a508d80a39951b440336ab7;p=thirdparty%2Fopenwrt.git

d1: enable overlay support

Add the loop module and mkfs tool to use f2fs/ext4
based overlays. This fixes the following bug:

mount_root: unable to create loop device
mount_root: no usable overlay filesystem found, using tmpfs overlay

Fixes: 99545b4bb1faf7c3 ("d1: add new target")
