From: Jo-Philipp Wich Date: Sun, 12 Apr 2015 18:20:01 +0000 (+0200) Subject: luci-mod-admin-full: simply fstab configuration X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=622cfc673ab2e97001ed394f8cd6d0425d8f3378;p=project%2Fluci.git luci-mod-admin-full: simply fstab configuration Simplify fstab setup by offering hints for uuid/label and device node options. Fix rootfs handling logic by removing obsolete references to the "is_rootfs" option and offering "/" and "/overlay" choices for the mountpoint instead.
