Using kernel v3.18.41, something unexpected happens when I mount two overlays. Once the second overlay is mounted, the binaries won't execute any more. Below is a simple script to demonstate the issue. Although this uses a shell script, the same thing happens with actual binaries. What am I doing wrong here? Thanks, Richard ---8<--- cd /tmp mkdir merged layer1 layer2 w1 w2 touch layer1/.layer1 layer2/.layer2 cat > merged/helo.sh <<-EOF #!/bin/sh echo helo EOF chmod +x merged/helo.sh mount -t overlay overlay \ -oro,lowerdir=/tmp/merged,upperdir=/tmp/layer1,workdir=/tmp/w1 /tmp/merged ./merged/helo.sh # works as expected mount -t overlay overlay \ -orw,lowerdir=/tmp/merged,upperdir=/tmp/layer2,workdir=/tmp/w2 /tmp/merged ./merged/helo.sh # -bash: ./merged/helo.sh: Invalid argument -- To unsubscribe from this list: send the line "unsubscribe linux-unionfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
