Allowing users to randomly write to devices could potentially lead to physical damage to the system and so isn't something we want to for example see distros enabling by mistake, and it's also a back door that people will happily use for working around the kernel in ill conceived ways. People who reasonably need this are edting their kernel anyway so tweaking the in code define isn't onerous. --Oiv9uiLrevHtW1RS Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.20 (GNU/Linux) iQIcBAEBAgAGBQJRqkJGAAoJELSic+t+oim92jEQAJcAr303X+i8Qv010KPybeYf wy7oyk9ZdBfOMzl5v2p2EvtGKC5E38f0wP1n/bFk5gfJ56WmL2UOtUEGQQRb4Ayo Xc0wclmScf7yj53rUGyGLXMslbIFnddUcYBbc8YJQ4feMj4qyusyAaI92tIQt9YH G+EzclP18ClC5N9kkLMuhGx/JkffQ753J9zQTMd3sZQ8T6rBWI5WjbaN0cAkuK6h MPvQ2v9bzyzuyORQrV4C0n7a9G9pR0wrEyoMqjf9R+hoLzANlgSCy4lugDRoVOdW MBsKdfkGG7j8vAiGPXf/hyWYrSlNbmEWdYSgR6M7ODepqXE2e6eej5zi5DIG0Qvh QW5ThfZ1dIy47KZ1ogIF1Ms1l656FM5ZMovxTzqJOb2QbmHVUxqU1A/sRBpQ4nik p1lLtvsOBHEqWpVG4Jv6Pws9/Ovrzl330hSiSrjBEuYFZYchJbB4YbbQYOL30Lew 7OydgaaR+VKMyfav/ISmMGkKw6OuYULI3pwg23s+45+WZwE9ZjU5rpYddZ/Wlk6W GPteVwWiKMgdvw/ap2i8oyCWvEUHY8hNUcjFnAxdHEjMitmwDe17sI1M1gbqrIk0 y37NNRIjp5jQNeMSjh6s/neZwz/bKWhoItrS59I6eFU9MKhl2SSDeMnG8SjNQIbY kX28plum3lAip/csrhRp =Wc2T -----END PGP SIGNATURE----- --Oiv9uiLrevHtW1RS--
