bind mounting /etc/resolv.conf fails #1523
Description
I'm trying to run a rootless container on a Linux machine.
How to reproduce
$ skopeo --insecure-policy copy docker://opensuse/amd64:42.2 oci:opensuse:latest
$umoci unpack --rootless --image singleuser:latest bundle
$ runc --root /tmp/^Cnc run test
container_linux.go:265: starting container process caused "process_linux.go:348: container init caused \"rootfs_linux.go:57: mounting \\\"/etc/resolv.conf\\\" to rootfs \\\"/home/yuvipanda/code/ferry-commute/bundle/rootfs\\\" at \\\"/home/yuvipanda/code/ferry-commute/bundle/rootfs/etc/resolv.conf\\\" caused \\\"operation not permitted\\\"\""
I suspect that the problem is related to the fact that my $HOME is mounted with encfs and has nodev & nosuid (maybe related to #1247?)
/home/.ecryptfs/yuvipanda/.Private on /home/yuvipanda type ecryptfs (rw,nosuid,nodev,relatime,ecryptfs_fnek_sig=bf2ce9e5622d0c40,ecryptfs_sig=ae8560bd6ae1015e,ecryptfs_cipher=aes,ecryptfs_key_bytes=16,ecryptfs_unlink_sigs)
