# Verify there is the correct OUTPUT=USB in $ROOTFS_DIR/etc/rear/local.conf # This script was added in 2011 as build/USB/default/80_enforce_usb_output.sh via # https://github.com/rear/rear/commit/4ec9ed4aa58787f42ad2946d68358d1de3417a60 # with only this git commit comment # "Make sure OUTPUT=USB is enforced in udev workflow during recover" # but the reason for this verification script is unknown, # see the description below and # see https://github.com/rear/rear/pull/3110 # and https://github.com/rear/rear/pull/3110#issuecomment-1862366094 # and https://github.com/rear/rear/pull/3103 # and https://github.com/rear/rear/issues/1571#issuecomment-343461088 # and https://github.com/rear/rear/issues/1571#issuecomment-343516020 local_conf_output=$( source $ROOTFS_DIR/etc/rear/local.conf ; echo $OUTPUT ) test "USB" = "$local_conf_output" && return # At this point we run this script build/USB/default/800_enforce_usb_output.sh # which means there is OUTPUT=USB in etc/rear/local.conf # (otherwise this script is not picked up by the SourceStage function) # cf. https://github.com/rear/rear/pull/3103#issuecomment-1860001618 # and https://github.com/rear/rear/pull/3103#issuecomment-1860169199 # but in $ROOTFS_DIR/etc/rear/local.conf there is not OUTPUT=USB # so somehow OUTPUT got modified in $ROOTFS_DIR/etc/rear/local.conf # after etc/rear/local.conf was copied via build/GNU/Linux/100_copy_as_is.sh # i.e. between build/GNU/Linux/100_copy_as_is.sh and build/USB/default/800_enforce_usb_output.sh # but as of this writing (19. Dec. 2023) nothing could be found in those build stage scripts # which modifies $ROOTFS_DIR/etc/rear/local.conf (at least nothing obvious was found) # cf. https://github.com/rear/rear/pull/3110#issuecomment-1862366094 # nevertheless it would be a bug in ReaR if OUTPUT got modified in $ROOTFS_DIR/etc/rear/local.conf LogPrintError "OUTPUT=USB is used but that is missing in $ROOTFS_DIR/etc/rear/local.conf" LogPrintError "See https://github.com/rear/rear/pull/3110 and follow the links therein" BugError "'rear $WORKFLOW' uses OUTPUT=USB which will not be used for 'rear recover'"
