From ab1785b1b2559c9f2d09d4d3ce43e11f4b828616 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Wed, 10 Jan 2018 20:17:48 +0100 Subject: build: fix restoring /etc/opkg with PER_DEVICE_ROOTFS When generating per-device rootfs directories, the ./etc/opkg/ directory is moved away prior to calling opkg install, opkg remove and rootfs_prepare. After the opkg invocations and the rootfs_prepare macro call, the saved opkg config directory is supposed to be moved back to its previous ./etc/opkg location. The mv command however can fail to properly restore the directory under certain circumstances, e.g. when the prior opkg or files/ overlay copy operations caused a new ./etc/opkg/ directory to be created. In this case, the backed up directory (named target-dir-$hash.opkg) will be moved into the preexisting ./etc/opkg/ directory instead, causing the opkg configuration to be located in a wrong path on the final rootfs, e.g. in /etc/opkg/target-dir-$hash.opkg/distfeeds.conf instead of /etc/opkg/distfeeds.conf. Solve this problem by replacing the naive "mv" command with a recursive "cp -T" invocation which causes the backed up directory tree to get merged with the destination directory in case it already exists. Also perform the rootfs_prepare macro call after restoring the opkg configuration, to allow users to override it again by using the files/ overlay mechanism.
