-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 mkdir /mnt/dev mount --rbind /dev /mnt/dev umount /mnt/dev The umount fails because of the sub mounts that the recursive bind also bind mounted under /mnt/dev, which you have to remove manually first. When you mount with --rbind, umount should be able to reverse the process, unmounting all recursively bound mounts. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk2lG2MACgkQJ4UciIs+XuK4gACght4RCHeo8vtnOLbU28Ymy5CL jBAAn3O7l4gKnVNqPUA/CXSO4aywSp13 =Fmfy -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe util-linux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
