Many people use it that way. Which means I can put it on an old Raspberry Pi B+ revision 1.2 board (which Wikipedia indicates as the B 1+ in the Specifications table but as Raspberry Pi 1 Model B+ revision 1.2 in the schematics of connectors).
I might consider DietPi as distribution (which is Debian based) as it is even ligher.
See [WayBack] https://www.reddit.com/r/pihole/comments/6h39zr/is_a_raspberry_pi_1_good_enough_for_a_pihole/#divw0i5
One more note: I need to check out which Debian base name (which indicates the version) works best as there seemed to be a dnsmasq issue (not archived because discourse hatesdislikes the WayBack machine and Archive.is):
Like Apple, Android and Delphi, they use name based versions of which I always forget the order of. Luckily the source of the below table gets updated over time [2017 Archive.is, 2018 Archive.is] Debian releases and names – Electric Toolbox Debian releases are named after characters from Toy Story and are frequently referred to with the name rather than the version.:
Version Code name Release date Toy Story character 1.1 Buzz 1996-06-17 Buzz Lightyear 1.2 Rex 1996-12-12 Rex (the T-Rex) 1.3 Bo 1997-06-05 Bo Peep 2.0 Hamm 1998-07-24 Hamm (the pig) 2.1 Slink 1999-03-09 Slinky Dog 2.2 Potato 2000-08-15 Mr Potato Head 3.0 Woody 2002-07-19 Woody the cowboy 3.1 Sarge 2005-06-06 Sarge from the Bucket O’ Soldiers 4.0 Etch 2007-04-08 Etch, the Etch-A-Sketch 5.0 Lenny 2009-02-14 Lenny, the binoculars 6.0 Squeeze 2011-02-06 Squeeze toy aliens 7 Wheezy 2013-05-04 Wheezy the penguin 8 Jessie 2015-04-26 Jessie the cowgirl 9 Stretch 2017-06-17 Rubber octopus from Toy Story 3 10 Buster not yet released Andy’s pet dog 11 Bullseye Not yet released Woody’s horse Sid “unstable” The next door neighbour

Need to watch these:
A few notes:
$ curl --silent --show-error http://example.org > /dev/null
Segmentation fault (core dumped)
$ curl --silent --show-error http://example.org > /dev/null
Most important bits of my external infrastructure – page 1
I thought I had forgot about the SuSEfirewall2 changes (On my research list: migrate from OpenSuSE SuSEfirewall2 to firewalld) so assumed that was the reason I broke one of my secondaries (which runs on a Raspberry Pi 2):
Mistakes like these are the reason to have secondaries in the first place https://infrastatus.wiert.me and do port-mortems.
Which is kind of odd, as the SuSEfirewall2 didn’t throw any warnings like at this similar one:
This one still works because it is on the firewall in front of the Raspberry Pi 2:
(Screenshots of the above URLs are below).
In fact it was another mistake: I had forgotten to make the DHCP lease static, which resulted in a wrong IP address to be assigned upon reboot, instantly making the firewall rules invalid:
I could have fixed this remotely when I had thought about this.

Some notes based on The woods and trees of OpenSuSE on single-board computers – image abbreviations – and getting it installed using OS X « The Wiert Corner – irregular stream of stuff.
I needed to get Ubuntu on an ODROID-C1+ (as it looks like nobody is maintaining a current OpenSuSE for it).
Download either of these (note that “minimal” is different from “mate minimal”; see https://www.youtube.com/watch?v=jOYWx_YToh8) from de.eu.odroid.in/ubuntu_16.04lts:
I installed on a 8 gigabyte SD card that revealed itself as /dev/disk1 using this diskutil command (via osx – List all devices connected, lsblk for Mac OS X – Ask Different [WayBack])
diskutil list
So this wrote the image to SD card in a sudo su - prompt:
targetDevice="disk1"
unxz --keep ubuntu-16.04-minimal-odroid-c1-20160817.img.xz; \
diskutil umount "/dev/${targetDevice}s1"; \
dd bs=1m of="/dev/r${targetDevice}" if=ubuntu-16.04-minimal-odroid-c1-20160817.img; \
sync; \
diskutil list; \
diskutil eject "/dev/${targetDevice}"
Use the default user and password that [WayBack] ODROID Forum • View topic – Ubuntu Minimal User / Password mentions:
odroid login: root
Password: odroid
From there, create a new user and add it to the sudo group (I used visudo to check the correct group for sudoers) :
adduser jeroenp
addgroup jeroenp sudo
And then hook it up to the network and get the IP address:
ifconfig
Now you can ssh into the odroid with user jeroenp and the password assigned to it. You can also perform a sudo su - to get to root level.
First of all, install etckeeper as it’s a life saver:
apt-get install etckeeper
This will install some other packages, but that’s OK; it will end suggesting you to enter email address, name and perform an initial commit:
Initialized empty Git repository in /etc/.git/ *** Please tell me who you are. Run git config --global user.email "you@example.com" git config --global user.name "Your Name" to set your account's default identity. Omit --global to set the identity only in this repository. fatal: unable to auto-detect email address (got 'root@odroid.(none)') etckeeper commit failed; run it by hand
Do that:
cd /etc
git config --global user.email "example@example.org"
git config --global user.name "Example User"
git commit -m "initial commit"
Now perform these steps:
Change root password:
# sudo su -
# passwd
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
Disable etckeeper daily autocommits involves one line in /etc/etckeeper/etckeeper.conf:
-#AVOID_DAILY_AUTOCOMMITS=1
+AVOID_DAILY_AUTOCOMMITS=1
Change the hostname; assuming your new host name is newHostName.
/etc/hosts and replace the old hostname with newHostNamehostnamectl set-hostname newHostName
exec bash
hostname -fBoth the command prompt and the hostname output should show newHostName.
Update/Upgrade:
apt-get update
apt-get upgrade
Fix the cursor in console mode:
Somehow the Odroid C1+ does not support a blinking hardware text cursor.

A cool set of YouTube videos by CWNE88:
The USB device used here is this one:
Tuner is AVerMedia AVerTV Volar Green
There are 2 models, but the good one uses firmware dvb-usb-it9135-02.fw The other one uses dvb-usb-af9035-02.fw but that didn’t seem to work as well and got hot. They look the same on the outside though.

Interesting as it has steps for both OpenSuSE and Debian each well suited for running on a Raspberry Pi.
[WayBack] MX Backup – Postfix Email Server | samhobbs.co.uk
It seems postfix is a lot easier to configure than sendmail so I already like it.
First I need to read a bit more in Postfix greylisting.
I’ll need to catch up on Sam’s other parts with the postfix tag as well:

Interesting stuff; I wonder if there is a case for it as well:
The Cluster HAT interfaces a (Controller) Raspberry Pi A+/B+/2/3 with 4 Raspberry Pi Zeros Configured to use USB Gadget mode, it is an ideal tool for teaching, testing or simulating small scale clusters.
This Kit Includes 1 x Cluster HAT V2, 4 x Raspberry Pi Zero’s, 4 x 16GB Micro SD Cards.
Please Note. A Raspberry Pi B+/2/3, with SD Card & Power Supply are also required for set up. These items are NOT Included in the Kit but can be purchased separately.
