A bit of KISS (Keep It Simple Stupid) in kubuntu ?

Re: A bit of KISS (Keep It Simple Stupid) in kubuntu ?

@kubicle: Indeed. In fact, what's even cooler: BlueDevil has been superseded by the SAME author that wrote kbluetooth

I already test BlueDevil on Lucid and even though I use it from Git, I have found no issues or bugs so far (except for the starting command which should be easier, but once started no worries there). It works like a charm and there are soooo much improvements over kbluetooth

But now I'm going offtopic, sorry :$

@dami: Even in System Settings>>>Autostart you can disable things like kbluetooth (not kmix and klipper). Klipper can be easily disabled via right click. And KMix is something almost all users want, so why should there be an option to disable it by default?
Looking at your answer, it seems like Arch has patched those programs to include the mentioned autostart tag.

/etc/sudoers.d/ (and all those d directories)

damipereira:

I have seen that but still don't understand what's the problem with 1 simple sudoers file, a whole folder seems too complicated

Rule of thumb

Don't edit (mess) the original setting files if possible - use the separate additional (d directory) files.


man sudoers:

The #includedir directive can be used to create a sudo.d directory that the system package manager can drop sudoers rules into as part of package installation...

The sources.list is another example (man sources.list):

SOURCES.LIST.D
The /etc/apt/sources.list.d directory provides a way to add sources.list entries in separate files.

Example

Giving a user (rog) rights to run an application (showfsck) without the root password.

Before:

sudo -K

sudo showfsck

[sudo] password for rog:
8/30 mount(s) until fsck for /dev/disk/by-uuid/b84b535f-f2b3-47bf-93b7-661a400f3bbc
8/31 mount(s) until fsck for /dev/sda2
25/32 mount(s) until fsck for /dev/sda5
26/33 mount(s) until fsck for /dev/sda6
29/36 mount(s) until fsck for /dev/sdb3
30/37 mount(s) until fsck for /dev/sdb4

Editing:

sudo visudo -f /etc/sudoers.d/01_exception

man visudo:

-f sudoers

Specify and alternate sudoers file location. With this option visudo will edit (or check) the sudoers file of your choice, instead of the default, /etc/sudoers. The lock file used is
the specified sudoers file with ".tmp" appended to it.

Adding there:

rog ALL= NOPASSWD:/usr/sbin/showfsck

Save and exit.

Check:

sudo cat /etc/sudoers.d/01_exception

rog ALL= NOPASSWD:/usr/sbin/showfsck

A bug report > Bug #580801: Default /etc/sudoers file overwrites /etc/sudoers.d for 'admin' users

=> Editing the sudoers:

sudo visudo

Adding another "#includedir /etc/sudoers.d" to the end of the sudoers file:

# /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the man page for details on how to write a sudoers file.
#

Defaults    env_reset

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification
root  ALL=(ALL) ALL

# Allow members of group sudo to execute any command after they have
# provided their password
# (Note that later entries override this, so you might need to move
# it further down)
%sudo ALL=(ALL) ALL
#
#includedir /etc/sudoers.d

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

#includedir /etc/sudoers.d

Save and exit.


After (testing):

sudo -K

sudo showfsck

8/30 mount(s) until fsck for /dev/disk/by-uuid/b84b535f-f2b3-47bf-93b7-661a400f3bbc
8/31 mount(s) until fsck for /dev/sda2
25/32 mount(s) until fsck for /dev/sda5
26/33 mount(s) until fsck for /dev/sda6
29/36 mount(s) until fsck for /dev/sdb3
30/37 mount(s) until fsck for /dev/sdb4

Re: A bit of KISS (Keep It Simple Stupid) in kubuntu ?

There is also this trick you can use to disable autostarting for specific users. Still not obvious, but should work over upgrades as long as the .desktop file name stays the same.

That's clever fix. What I had to do was delete the "/usr/share/autostart/bluetooth.desktop" and -x the "/etc/init.d/bluetooth" for the bluetooth to stop. Using either or wouldn't work. I needed to do both. Maybe the "Trick" will do the trick
