Makefile:287: recipe for target '/mnt/ramdisk/koen/firmware/builds/owrt_mt76x8/build_dir/target-mipsel_24kc_musl/linux-ramips_mt76x8/tmp/openwrt-ramips-mt76x8-netgear_r6120-squashfs-factory.img' failed Debugging using valgrind shows stack corruption due to a buffer overflow. The author of the generator assumes the filename ends with "root", while it should be "rootfs". Fix this by accounting for the 2 missing characters which solves the build issues. More work is required to cleanup this source, which will be done later on.
