Based on this excellent guide.
WARNING: You’re going to be messing with hard drives. You’ll probably be doing most of this as root. As the old adage goes, “The good thing about Linux is that it does exactly what you tell it to do. The bad thing about Linux is that it does exactly what you tell it to do.” I strongly recommend you to disconnect/remove drives you don’t want touched during this procedure so you don’t inadvertently wipe a disk you don’t want wiped.
Note: at the time of this writing, KDE Neon is based on Ubuntu 16.04 Xenial.
The whole process looks something like this:
- Boot into Xenial Desktop live environment
- Install ZFS packages in live environment
- Prepare array
- Debootstrap base system into array
- Chroot into array
- Install the rest of KDE Neon
- Reboot into new KDE Neon system on ZFS

Managed to get Chinese input on KDE Neon using
fcitx. These are the packages I have installed:
To start at login:
sudo cp /usr/share/fcitx/xdg/autostart/fcitx-autostart.desktop /etc/xdg/autostart/
I was having an issue where the
fcitx configurator window would pop up at login, which I did not want. I edited the
Exec= line as shown, which seems to have alleviated the problem:
Not sure why
fcitx-autostart also opens
fcitx-configtool at login. If I close everything and run
xterm, it does start the little systray applet thing, but not the configurator. From what I can tell, it only opens the configurator when it runs at login.
sudo apt update
sudo apt dist-upgrade
sudo apt install qml-module-org-kde-kcm

Handy little guide on setting up git repos locally.
If you’re you’ve got PasswordAuthentication set to no in your sshd_config, you need to disable it temporarily to copy the keys as the user you normally use using ssh-copy-id git@localhost. Once the key is successfully copied, then you will no longer be prompted for a password.. and you can re-disable Password authentication.
Geeked out pretty hard this weekend! Bit of a convoluted process but I’m happy with the way things are going. Laptop is free to run Windows for vidya. Raspberry Pi 3 does my dinky Linux server stuff.
Re-partitioned the drive in the Windows laptop to have a bit more room for the break-in-case-of-emergency Linux partition (which I still need to install).
Bought a Raspberry Pi (and related party supplies) near GuangHua Tech Plaza in the underground market. Split off everything but /boot onto a 500GB external HDD so as not to kill the MicroSD card.
While the laptop is a less-than-ideal piece of gaming hardware, it is sufficient for my purposes, especially now that it doesn’t need to do Linux duties anymore.
Still need to iron out Bluetooth connectivity with the PS4 controller..
Following this guide I set up ELK stack in a VM. Currently only getting logs from my www server, but will add others later. Also need to mess with grok.
This is an error I get when starting MySQL on a Galera cluster node after a reboot.
The result of this is that MySQL fails to start automatically after a reboot. I have no idea why this is happening and the error appears to be extremely rare, as there (from what Googling I’ve done so far) is very little discussion of this issue, except for this guy. I’ve reached out to him on Twitter; we’ll see what he says.
I would hope that there’s a way to make this fix permanent. Because of it’s location I cannot expect that directory to be persistent across reboots. I want to say that this is some issue with MySQL not doing what it needs to do start itself up properly (i.e. making the directory in /var/run that it needs to make) but perhaps the blame is on the OS (or, more likely, me).
I don’t know if this is a bug or not, but I know I don’t have this issue with MySQL sans-Galera.
Elsewhere, I’ve been suggested to examine this post for more information how I might remedy this issue.
