Related reports: https://bugzilla.altlinux.org/show_bug.cgi?id=9683 (doesn't bring down an iface declared DISABLED (instead of my intention to stop the network)) https://bugzilla.altlinux.org/show_bug.cgi?id=16910 (doesn't bring down an iface after a change in the configuration which makes the iface unknown/disbaled) I think that a general rule could be assumed (such that most users will agree with it): if the intended state of a certain iface in the new state of the network is down (it is declared disabled in the new profile, or the whole network is brought down), then it must be brought down. An "exception"/different case might be the case when an iface is unknown in the new profile/configuration: then there is simply no intention stated about it, and it can be left up. В 4.1/branch исправления не будут вноситься уже технически (заглушена очередь на сборку), поэтому прошу ошибки, актуальные для sisyphus/p7/t7, перевесить на текущие ветки или сизиф. |

Expected: all ifaces which are up or at least those ifaces which have been brought up by etcnet are brought down by "service network stop". Workaround: use the ugly "stopwith": [root@localhost net]# service network stopwith Auto Computing interface groups: .. 2 interfaces found Processing /etc/net/vlantab: empty. Stopping group 1/realphys (1 interfaces) Stopping lan: ....OK Stopping group 0/virtual (1 interfaces) Stopping lo: OK [root@localhost net]# ifconfig [root@localhost net]# (But that's very illogical: I mustn't remember the name of the profile which was used. Also: the config files might have changed between the "startwith" invocation and "stop". So, etcnet should care about bringing down the actual ifaces.)
