Interesting. Outside the chroot:
drwxrwxrwt 2 root root 40 Jun 29 10:55 /run/shm
Inside the chroot:
drwxr-xr-x 2 root root 40 Jun 29 10:55 /run/shm
Since when does bind-mounting change the file mode bits?
Are we losing because /run/shm is already a tmpfs prior to bind-mounting? Should we clobber it manually, or is there a better way to do this?
