1 Motivation
════════════
Manjaro is a nice OS in general. But there are some issues (Robertson
2022a) like polybar fails for some weeks because Manjaros repos update
two week after Archs', so the AUR is out of sync with them.
It was a good starting point for me to experience Linux; now I feel
confident enough to use bare Arch.
2 Process
═════════
2.1 Backup
──────────
It's possible, if having the `/home' folder in its own partition, to
install a new linux system and keep the data. But there is the risk of
overwriting it, therefore a Backup is recommended in any case.
2.1.1 System
╌╌╌╌╌╌╌╌╌╌╌╌
To get a list of the currently installed packages, I stored the output
of `pacman' into a file.
┌────
│ pacman -Qeq > package-list.txt
└────
Listing 1: list of programms
(just lists the /explicit/ installed packages.)
This way, I /could/ simply push this list into pacman to get the same
packages as now; but I'll rather use it to look at it if I need to and
don't install all the unused packages too.
2.1.2 Data
╌╌╌╌╌╌╌╌╌╌
To backup my personal data, I plugged in an old HDD. It was named
`/dev/sda1'. So I mounted it and archived my whole home-directory into
it. While doing so, i ran into some errors.
1. When doing my first try, I was logged in as `adrian'. At the very
end complained about changed files. Conclusion: don't be logged in
while cerating the backup.
2. By trying different compressions, I found that it's faster to just
throw the data uncompressed at the drive than using something like
. My initial thought was that the slow HDD would be the smallest
part in the pipe, but it was the compression.
So I logged in as `root', mountet the HDD and stored my data onto it.
┌────
│ mkdir ~/media
│ mount /dev/sda1 ~/media
└────
Listing 2: mounting the HDD
┌────
│ tar -cvf media/Backup/2022-09-15.tar /home/adrian
└────
Listing 3: backup the data

2.2 Install-stick
─────────────────
I just downloaded an Arch-iso from some mirror (“Arch Linux -
Downloads” 2022) and wrote it on the usb-drive. (The stick was
connected as `/dev/sda'.)
┌────
│ pv archlinux-2022.09.03-x68_64.iso > /dev/sda
└────
Listing 4: writing
2.3 Installation
────────────────
The installation is relatively simple. (“Installation guide -
ArchWiki” 2022)
1. make the computer boot from the usb-drive
2. the arch-iso loads
3. run (archlinux 2022) and fill in all the information
I let the installer whipe the whole disk, created a user `adrian'
again, set up language, time, keyboard and installed i3wm
(Developers 2022) as a window manager.
2.4 Get the data back
─────────────────────
Now I had a functional Arch-System with nearly empty home directory. I
took the HDD, mountet it and moved the data back. I did it again as
`root' to prevent any more difficulties.
┌────
│ mkdir ~/media
│ mount /dev/sda1 ~/media
└────
Listing 5: mounting the HDD
┌────
│ tar --skip-old-files --file media/Backup/2022-09-15.tar /
└────
Listing 6: get the data back
Notice
1. the flag, which I used to pause and resume the extraction to get
sleep without the noise of the HDD.
2. the location is specified as and not as , because the archive
already contains the information about where the data goes.
2.5 Ready!
──────────
┌────
│ pfetch
└────
┌────
│ /\ adrian@archlinux
│ / \ os Arch Linux
│ /\ \ host 81LG Lenovo IdeaPad L340-15IWL
│ / \ kernel 5.19.8-arch1-1
│ / ,, \ wm i3
│ / | | -\ uptime 6h 23m
│ /_-'' ''-_\ pkgs 791
│
└────
Now I run Arch. Browser, Matrix-client etc. work all like before on
Manjaro, because their userdata is unchanged. I've already installed
some missing packages as I ran into errors in my daily workflow (one
because of a bug in Doom Emacs (doomemacs 2022) which I installed
manually), and there are still some missing. Nevertheless There are
only 791 packages installed currently. On Manjaro I had more then two
thousand installed!
3 Another Installation <2022-09-30 Fr>
══════════════════════════════════════
After two weeks, I decided to install it again. The main reason is,
that `archinstall' decided the `/' Partition should only get 20GB,
which is not enough for all the software I use. Also I
⁃ use Systemd-boot, because Grub has some annoying problems (Robertson
2022b)
⁃ use no preslected profile (like i3wm which would install all stuff
to make i3 run), because I made a new package-list which I just read
in before the reinstall
3.1 Problems
────────────
I run into the same problems this time, as last time. But this time I
was prepared for this and documented my way solving them.
⁃ No Internet connection
┌────
│ systemctl enable systemd-networkd
│ systemctl start systemd-networkd
│ systemctl enable systemd-resolved
│ systemctl start systemd-resolved
│ pacman -S NetworkManager
│ systemctl enable NetworkManager
│ systemctl start NetworkManager
└────
Listing 7: enable network
• `systemctl' enable and start `systemd-networkd',
`systemd-resolved'
• install `NetworkManager' and `systemctl' enable and start it's
⁃ For some reason, the locale wasn't set right. So I had to edit the
`/etc/locale.conf' and `/etc/locale.gen', then run `locale-gen'
┌────
│ LANG=de_DE.UTF-8
└────
Listing 8: /etc/locale.conf
┌────
│ #...
│ de_DE.UTF-8 # (comment out the needed language)
│ #...
└────
Listing 9: /etc/locale.gen
┌────
│ sudo locale-gen
└────
Listing 10: generate locale
3.2 Get the packages back
─────────────────────────
First, I needed to get paru (“AUR (en) - paru” 2022), a very useful
AUR-helper.
Following the instructions on it's github-page, I installed `git' and
`base-devel', cloned it *as a normal user*, then `mkpkg -si'.
Afterwards, I could simply push the List of packages into it.
┌────
│ paru -S $(cat ~/media/package-list.txt)
└────
Listing 11: reinstall the packages
3.3 Ready!
──────────
Now I use Arch again, but
⁃ The `/' partition will not run full unless my `/home' is full too
(because both are the same)
⁃ by using `systemd-boot' instead of `grub' I don't risk any issues
⁃ By Installing it a second time, I got better in getting the network
work. (last time I tried so many things, that I couldn't write about
it, I just hadn't known what made it work)
