Subject: slugos-init: Use tune2fs to mark the root fs with a "unique" label
X-Git-Tag: Release-2010-05/1~9453^2~2598
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ec31c75e94546c0ede50107715ade3920516834f;p=openembedded.git

slugos-init: Use tune2fs to mark the root fs with a "unique" label
turnup marks the rootfs with a label, and /boot/disk mounts the correct
partition on boot.
Closes slugbug #320
