comment How to remove element from gsettings array in script?
Works flawlessly if the element is actually present in the list (easy to check with gsettings get ${schema} ${key} | grep -q "${value}" )

comment How to install ubuntu to a already encrypted partiton without formatting it in 14.04
Thanks to subvolumes you can share btrfs root partition between distros. And if it is unencrypted, you have no headache with instalation. After all, as long as your system is uninfected, there is very little opportunity for your private data to slip out outside /home - the only other folder in which you have write access is /tmp (but it is in ramdisk (tmpfs) ) and swap, which is encrypted by default by installer with one time passwords if you use "encrypted home folders".

By "simple" I mean: all your sensitive data in dedicated LUKS partition, independent from system. This way you have easy backup/restore procedures (your data are kept separate from OS). And exta features from both ecryptfs and LUKS, like easy dualboot with other distro, no limits to filename length, possibility to deduplicate files with tools like bedup, possibility to share the system with your friend(s) without fear of disclosure all you private stuff... I'm happy with such configuration.

I use "encrypted home", it uses ecryptfs. It has many important draw backs, but it is standard, and is mounted only if you know your login password. In the /home/user folder I store LUKS' key. It is used by my custom upstart script, that automatically mounts my LUKS volume with documents with that key, after successful login.

I can suggest walkaround: don't encrypt /, use standard encrypted @home only to store the LUKS encryption key, that mounts your private data. This way you keep on using unencrypted root which usually doesn't contain sensitive data anyway, and thanks to using LUKS you are not limited with size of filename and you can bedup duplicates. Keeping things "standard" makes life much easier.

I've never tested it without separate /boot partition.

comment Installing 14.04 Server to exisiting btrfs subvolume
if you want to install Ubuntu on existing btrfs partition, just make sure, that there are no @ and @home subvolumes on it. Those volumes will be created by installer automatically, and you can change their name later (remember to update grub and /etc/fstab !). I've never installed ubuntu on btrfs RAID though.

comment How to change number of workspaces from command line?
As I understand, gsettings is a preferred over dconf. It offers higher-level access to the dconf database. But I might be wrong.

comment Can I enable bash-completion for the new apt command?
@Oli Oh, you are right! I didn't know about it. And - bash-completion doesn't support it out of the box so far. Fortunately it wouldn't be that difficult to write a plugin, so you can expect one soon. Chances are, that using my script you would be among the first, who can use it.

@Oli Well, I guess they do. There are files aptitude, apt-get and apt-cache. What exactly do you mean by apt completion?

comment lxc container creation fails with `call to cgmanager_move_pid_abs_sync(blkio) failed: invalid request` (…)
@Braiam I understand. I use classical, stand-alone Ubuntu 14.04 installed on a physical notebook as a LXC host.

@Braiam no. I didn't try LXC on VMWare/VirtualBox guest, if that is what you ask. But why is that relevant? LXC should be independent from hardware virtualization.

comment How to add “exotic” keyboard layouts on Ubuntu?
Looks promising, but I fear that it may not do stuff "the Ubuntu way", and so might interfere with the system components. I've never tried it, though.

comment Any chance of installing Ubuntu on existing bcache device formatted with btrfs?
@ignis You are right. I don't think that these two mix up well due to some bugs. I had to scrap my btrfs root partition because of this. My experience is similar to this one: webcache.googleusercontent.com/…

comment Any chance of installing Ubuntu on existing bcache device formatted with btrfs?
@psusi Oh. Do you know then, how to load the bcache module and rescan all the block devices to identify bcache volumes inside them? I tried hard to read everything about bcache usage on the web, and couldn't find anything equivalent to e.g. pvscan for lvm2.

@psusi bcache doesn't work until you reboot - it needs to add a kernel module. So you need modify the dvd in a way that survives reboots.

That would solve the problem. I don't have any expertise in mastering livedvds, but I'll look into it.
