comment How to use ubuntu as a bluetooth headset to the mobile phone?
None. For the moment I just accepted the fact, that Ubuntu ain't a microphone... ;-) I hope someday someone finds a way how to do it.

comment How to modify rootfs of an unprivileged LXC container?
Cool. I built a whole /etc/subuid parser exactly for this purpose...

comment Completely Uninstall Steam and ALL steam games
There is also a ~/.steam directory to remove. It contains EULA and some symlinks. Delete that too.

comment How to change mapping for the «PowerOff» key on keyboard?
YES!!! But then there is another thing: how to map it into the «end» key?

comment How do I setup an encrypted swap file?
@muru On Ubuntu 14.04 there is no need for such script. If I recall correctly, the early booting scripts parse the /etc/crypttab for a line like cryptswap /dev/sda5 none luks and asks the user for a password autmatically

comment How to let built-in DHCP assign a static IP to LXC container based on name, not MAC address
Restarting the service lxc-net is only needed to let the dnsmasq use configuration from /etc/lxc/dnsmasq.conf (and this piece of information is present in the /etc/default/lxc-net which is unknown to the dnsmasq). If you had it set before, just another SIGHUP should suffice.

comment How to let built-in DHCP assign a static IP to LXC container based on name, not MAC address
I like the idea of delegating list of hosts to a external file. Besides that, your method differs from mine because of the killall -s SIGHUP dnsmasq. I agree, that just "SIGHUP-ing" dnsmasq is more efficient then restarting the whole daemon (especially if it doesn't work without patching its upstart scripts).

comment Mount and access similar BTRFS filesystem
I'm sorry, I misunderstood your question. It looks like a bug on part of btrfs. If I were you, I'd ask on the btrfs.wiki.kernel.org/index.php/Btrfs_mailing_list (and if you do, please post some feedback here as well!)

comment Mount and access similar BTRFS filesystem
Just mount. If the volume is not part of btrfs raid (which I have no experience with), the volume should mount just fine. And as you mentioned, all subvolumes will be accessible too. You can get a list of them with sudo btrfs subvolume list <path inside the mount point>

comment Is it possible to use services that provide their own pid, like dnsmasq, to use with upstart?
Wow! Too bad I learned it so late. I already spent two days cooking my own version of Serge's upstart scripts...

True, but then there is nothing to protect you against giving two guests the same IP. See my accepted answer - it solves the problem.

@EvrenBingøl Try my answer. It works partially, but it is definitely a step in the right direction.

comment How to let built-in DHCP assign a static IP to LXC container based on name, not MAC address
It works only if the script can shut down the lxcbr0 network, which excludes the case when there are other lxc containers running. In short, as it stands now, you cannot assign static dhcp leases without restarting all the containers.

@HRJ On Ubuntu 14.04 restarting lxc-net doesn't help if you don't remove your lxcbr0 bridge. See my answer.

Yes, indeed! I should probably file a bug report to ulatency project.

comment Set default language to English (US) in 12.04
That dragging the grayed out entries is IMHO completely unintuitive. Grayed-out things usually are inactive, hence not-responding to mouse clicks.

I can confirm, that this worked for me - after the primusrun had seemingly spontaneously ceased to work.

comment Increasing partition size with unallocated space to the left
It is important to stress, that the target partition must not be mounted. If mounted, the gparted's interface will fail to show you the possibility of moving to the left without any explanation why it can't.
