We have to *guess* that doing this in fstab works: /some/old/dir /some/new/mountpoint ??? bind ??? ??? and it's not clear what is or isn't permitted for ???. Please consider amending mount(8) so the options listed under -o include something like this: bind same as --bind (other mount options are silently ignored) [...] rbind same as --rbind (other mount options are silently ignored) Isn't it also time to update the SYNOPSIS in mount(8), now that linux versions >=2.4.0 will be standard ? I suggest adding two lines like this: mount { --bind | -o bind } olddir newdir mount { --rbind | -o rbind } olddir newdir or, possibly, just one line mount { --bind | --rbind | -o bind | -o rbind } olddir newdir Thanks for your work. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJS9Q9fAAoJEI5FoCIzSKrwvJcIAJAzpyfRhoqBUred3klaeoVC MKxWyFlKmfj0qf18KrWcqxdDG2wssXPLkDexCOfD32ZPDUbnJol8BCc237b7TNVe gU3NJQXZ3WrmwzeGO6+0HVHdSiu0QR2vgMHYda7q+xHhyIyEhZFwl2vHoRf4HXNm 3hd5CeINnz9eu8Zh/h7BFbj+bZFMu7HVlb/IoTT7aByMqCLv+yJvB0+vOOSHFkmU AEBvEJix8DxwNDyXcq4LniifvrvxeG70B6AY8ZGLumano3I2BpYYu9a/LdUNv+lN JtiRffmEXk+joeTy8rosKWj7XI12Jabb5+PXUAHg4nxZKzP3I0HUF6UcAiDsoJY= =WglM -----END PGP SIGNATURE-----
