From: Matthias Schiffer Date: Mon, 10 Jul 2017 16:37:25 +0000 (+0200) Subject: base-files: automatically handle paths and symlinks for RAMFS_COPY_BIN X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=438dcbfe74a6da1a8949d8fb785092d934499b60;p=openwrt%2Fstaging%2Fdangole.git base-files: automatically handle paths and symlinks for RAMFS_COPY_BIN Depending on busybox applet selection, paths of basic utiilties may differ, and may not work as symlinks to busybox. Simply using whatever binary is found in PATH and detecting symlinks automatically is more robust and easier to maintain. The list of binaries is also slightly cleaned up and duplicates are removed.
