Reasoning.

I have a file server with Slackware running on a Pi4. I wanted to make the
movies and TV Shows easily accessible on the TV without using a DVD or Blu ray
player.

It would give my wife and I a chance to sit and watch a show without much
fuss. The latest show we are on is Sue Thomas F.B. Eye.
The main character, Sue has been deaf from about the age of 4 years.
She is adept at reading lips and learned to speak despite being deaf.

Hardware.

The Pi4 is enclosed in a stripped out power supply that died on me. The fan
still worked, so I wired it to the Pi on the 5v line. It runs at half the
speed it was designed for, but that makes it run almost silent. With the
heatsinks added, stays about 35C when idle and 50C when encoding video.

Pi Networking.

I have 2 Pi's connected via ethernet. One is on 192.168.2.5 with a gateway of
192.168.2.6, with the other on 192.168.2.6 with a gateway of 192.168.2.5.
Essentially just a crossover network. The reason for this is running Kodi on Pi4
has choppy video, but is better at running video encoding. So I linked it to a
Pi3 to run Kodi via a samba share from the Pi4.

Used OSMC for the kodi interface.
It was the distribution that was stable on my Pi and booted right to the Kodi
interface.

Installing Slackware.

Get sources
https://sarpi.fatdog.eu/index.php?p=getslack

root@mynixbox:/tmp# mkdir /slackarm
root@mynixbox:/tmp# mount /dev/sdc1 /slackarm
root@mynixbox:/tmp# cd /slackarm
root@mynixbox:/slackarm#

To download Slackware ARM 14.2, type the following at the command prompt:

root@mynixbox:/slackarm# rsync -Prv --delete
ftp.slackware.uk::slackwarearm/slackwarearm-14.2 .

[FatDog says ...] DON'T forget the period "." at the end of the rsync command
or it won't work!

I made a directory called extras, under the /slackarm directory

After mounting the sd card listed by the lsblk command, run
cfdisk /dev/mmcblk0 to partition the card.

Edit:

Since I sent the show notes, I had problems using the GUI way to set up
a static IP address on the OSMC section. Here is a more concise way to go about it.

https://discourse.osmc.tv/t/solved-setting-ip-static/1439/14

It seems OSMC uses connman, so in order to create an ethernet static IP:

1. Create a config file with your editor:

   sudo vim /var/lib/connman/osmc.config
   

2. Add the following contents:

   [global]
   Name = OSMC
   Description = OSMC static network configuration
   [service_osmc]
   Type = ethernet
   IPv4 = 192.168.0.21/255.255.255.0/192.168.0.1
   Nameservers = 8.8.8.8,8.8.4.4
   

   Make sure to change the IPv4 line to match your own network/netmask/gateway and Nameservers to use the ones you want.

3. Reboot your RPi or restart the connman service:

   sudo systemctl restart connman
   

If you opt to restart connman, you’ll loose the connection.
