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
• Tweak
• 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:

sudo apt install fcitx fcitx-bin fcitx-config-common fcitx-config-gtk fcitx-data fcitx-frontend-all fcitx-frontend-gtk2 fcitx-frontend-gtk3 fcitx-frontend-qt4 fcitx-frontend-qt5 fcitx-module-dbus fcitx-module-kimpanel fcitx-module-lua fcitx-module-x11 fcitx-modules fcitx-ui-classic im-config libfcitx-core0 libfcitx-gclient0 libfcitx-qt5-1 libgeoclue0 libgettextpo0 libjavascriptcoregtk-4.0-18 libpresage-data libpresage1v5 libtinyxml2.6.2v5 libwebkit2gtk-4.0-37 libwebkit2gtk-4.0-37-gtk2 presage zenity zenity-common fcitx-libpinyin

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:

...
#Exec=fcitx-autostart
Exec=fcitx
...

Not sure why fcitx-autostart also opens fcitx-configtool at login. If I close everything and run fcitx-autostart from 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.

Overview

1. Enable USB boot mode on the Pi (enables booting via network)
2. Setup dnsmasq on the server (provides /boot)
3. Setup NFS on the server (privides /)

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..

update `ofUser` set plainPassword = ‘admin’, encryptedPassword = null where username = ‘admin’;

See if this helps 😉

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.
