Hi!
After 'unshare --map-root-user --mount' and ensuring that /var/run/netns
is writable (possibly by binding another directory there), a network
namespace can be created by running 'ip netns create test'.
However, 'ip netns exec test sh' exits when it attempts to
unmount /sys. I don't think that the failing to umount /sys should be a
fatal error, because the following mount call ensures that /sys has the
right contents. I checked that 'ip netns exec' works fine when the
error returned by umount is ignored. Should I submit a patch to
iproute2?
Please CC me, because I'm not subscribed to the mailing list.
Greetings,
Robin Kreis
