It seems to do something similar. logind can be used to know the list of existing user sessions and which have console access, it also creates and to some extent manages cgroups but it doesn't do anything that the device namespace would at the kernel level. The main benefit from having a device namespace in the kernel would be to only get the uevents and device access for devices that are either owned or shared with the container. Being able to have fake devices replace some of the standard ones would also be nice to have. --=20 St=E9phane Graber Ubuntu developer http://www.ubuntu.com --JBi0ZxuS5uaEhkUZ Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAEBCgAGBQJSJjoGAAoJEMY4l01keS1n4AgP/2hPVARn1h8XjNPR+PKBebbf Iu1VS5yuAr7UZ+4HsBhqESynBHEcyswMRTQQstOF5yOQVVGgg10RZuJB0Lgq3uE5 rj8gZf9CCD2fBvB4NR3IdcGoDiqgGlg8O8+CnIoExZP7iGHqujvpUWSLEfbLTknK v6A7BP8eabQBsaVtjsSXj8v+OU4dz4BGlI6pMjplX350sPNm/tpJE6KIrmvXNzW1 uIP7NTCuwZ2wSDf7M7MC+vgPmjFDBxYJDwJdaveAY++H0esVXzd2yhxPL69o2cqL SQ9+Mbs+MM6rKWulEV7oRVP4F8OkjoLyZVVr/sTz9m24lFK3xDAbxmgzT9cz7H7b XvPfe+Ji6/cjH9Khu2eF03ReCk4lnUMCS3ZgzbJN3wsn3DbGPkQoo6viFjQiFCIs GiDQu96xLH5a6YMsglALhxUrXynosaI6lsEZAVjHuRNeMgLDT/47iRsaWCjznf6z Xll8zdf/945/Q0LznCL/4u0dHTF6leq5oVUZ0gYAfE+I9HHN4FFqeoc/D/HxZJj4 y4+fEOtJDCYaTOB7pB7N7oM2CrcKaVyLJfm2SaReOnfeeTu0AwJWmhT3aRGKRPtU z2NsBJJWVbx9rAEBVGj+P/buNxatfYHclvypLQmyC/xE7UitEYCXh7LvW959ZO5b Nm4YOjSMSPu523ck6wLz =xu29 -----END PGP SIGNATURE----- --JBi0ZxuS5uaEhkUZ-- --===============0660383653860012236== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Containers mailing list Containers-cunTk1MwBs9QetFLy7KEm3xJsTq8ys+cHZ5vskTnxNA@public.gmane.org https://lists.linuxfoundation.org/mailman/listinfo/containers --===============0660383653860012236==--
