# Motivation
Manjaro is a nice OS in general. But there are some issues (<a href="#citeproc_bib_item_7">Robertson 2022a</a>) 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.
<a id="process"></a>
# Process
<a id="backup"></a>
## 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.
<a id="system"></a>
### System
To get a list of the currently installed packages, I stored the output of `pacman` into a file.
pacman -Qeq > package-list.txt
(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.
<a id="data"></a>
### 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
tar -cvf media/Backup/2022-09-15.tar /home/adrian
<a id="install-stick"></a>
## Install-stick
I just downloaded an Arch-iso from some mirror (<a href="#citeproc_bib_item_2">“Arch Linux - Downloads” 2022</a>) and wrote it on the usb-drive. (The stick was connected as `/dev/sda`.)
pv archlinux-2022.09.03-x68_64.iso > /dev/sda
<a id="installation"></a>
## Installation
The installation is relatively simple. (<a href="#citeproc_bib_item_6">“Installation guide - ArchWiki” 2022</a>)
1. make the computer boot from the usb-drive
2. the arch-iso loads
3. run (<a href="#citeproc_bib_item_1">archlinux 2022</a>) 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 (<a href="#citeproc_bib_item_4">Developers 2022</a>) as a window manager.
<a id="get-data-back"></a>
## 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
tar --skip-old-files --file media/Backup/2022-09-15.tar /
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.
<a id="another-installation-2022"></a>
## 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 (<a href="#citeproc_bib_item_5">doomemacs 2022</a>) 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!
<a id="-another-installation"></a>
# Another Installation <span class="timestamp-wrapper"><span class="timestamp"><2022-09-30 Fr></span></span>
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 (<a href="#citeproc_bib_item_8">Robertson 2022b</a>)
- 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
<a id="problems"></a>
## 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
- `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
#...
de_DE.UTF-8 # (comment out the needed language)
#...
sudo locale-gen
<a id="get-packages-back"></a>
## Get the packages back
First, I needed to get paru (<a href="#citeproc_bib_item_3">“AUR (en) - paru” 2022</a>), 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)
<a id="ready"></a>
## 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)
