Basic system management

Inspecting the logs

Cockpit contains a viewer that is pretty similar in capabilities to yast2-journal.

The initial situation

The third field of /etc/shadow contains the date of last password change. It can contain:

• An empty string: means that aging features are disabled
• A zero: means the user must change the password in next login
• A set of digits: represents the date of the latest password change

We currently have this, which doesn't fly because we cannot distinguish if a value of nil really means that aging is disabled or simply that we do not know the date/state, for example for a new user that is not written to /etc/shadow yet.

I got early access to all the individual answers. Things I see mentioned several times:

• About the installation:
  • Quite some people say it should be simpler
  • Most concrete complaints are about how hard is to setup the storage and the WiFi.

Moving qgroup probing/editing to libstorage-ng

Reasons to do it

• The same mounting used to probe the subvolumes could be used to probe the qgroups.

• The same mounting used during the libstorage-ng's commit phase to create the subvolumes could be used to modify the qgroups.
