Just to be clear
- you have computer A with your configuration
- you now posess computer B which you will install with Manjaro
- apply the same configuration on computer B as you have on computer A
- in this context configuration is the files and folders found in
- $HOME
- /home/$USER
- ONLY user configuration is supported
There is so many ways this can be e.g. konsave (AUR). When you are using Plasma this [Tip] Save your Plasma configurations and easily switch between them will help you setup konsave.
I have a script I made for the sole purpose of replicating a setup.
The script is self explaining [root tip] [Utililty Script] Backup configuration and package list and all you have to do is adjust the variables for which data you want to transfer.
On computer A
- do a full system update and reboot
- verify your system is functional
The script creates three (3) files in the directory you specify - e.g. an USB stick
- a list of repo packages
- a list of custom packages
- a tarred archive with the configuration
On computer B
Navigate to the USB stick and open a terminal
Install repo packages
sudo pacman -Syu base-devel - < repo-pkglist.txt
Install custom packages
pamac build --no-confirm $(cat cust-pkglist.txt)
Extract the files
tar -xzf --overwrite ---directory $HOME dotconf.tar.gz
