[systemd-devel] [PATCH] nspawn: ignore EEXIST when mounting tmpfs

[Richard Schütz]

commit 79d80fc1466512d0ca211f4bfcd9de5f2f816a5a introduced a regression that
prevents mounting a tmpfs if the mount point already exits in the container's
root file system. This commit fixes the problem by ignoring EEXIST.
