| | Detailed [[https://docs.microsoft.com/en-us/windows/wsl/basic-commands#import-a-new-distribution|--import]] example: |
| | |
| | * We assume that we have an exported installation tar file available |
| | * In this example, we use the compressed backup file created in [[other:win10wsl#backup_of_a_full_linux_installation|Backup of a FULL Linux installation]]\\ ''C:\Scratch\<your_login>\WSL\WSL_Ubuntu_20.04.5_LTS_stdu_22-08-29.tar.gz'' |
| | * Create the directory where the Linux installation (mostly its ''ext4.vhdx'' file) will be restored |
| | * Hint: use an explicit directory path and name using the name of the distribution that will be restored\\ e.g. ''D:\WSL_Distributions\Ubuntu_custom'' |
| | * Import the distribution, giving it a name that does not appear in ''wsl -l -v'' |
| | * <code>> wsl -l -v |
| | NAME STATE VERSION |
| | * Ubuntu Stopped 2 |
| | |
| | > wsl --import Ubuntu_custom D:\WSL_Distributions\Ubuntu_custom C:\Scratch\<your_login>\WSL\WSL_Ubuntu_20.04.5_LTS_stdu_22-08-29.tar.gz |
| | |
| | > wsl -l -v |
| | NAME STATE VERSION |
| | * Ubuntu Stopped 2 |
| | Ubuntu_custom Stopped 2</code> |
| | * After importing, there should be a new ''ext4.vhdx'' file in the previously empty ''D:\WSL_Distributions\Ubuntu_custom'' directory |
| | * Start the imported ''Ubuntu_custom'' distribution |
| | * Directly from the Windows Terminal pull-down menu |
| | * Or from a PowerShell, using ''wsl --distribution Ubuntu_custom'' |
| | * WARNING: even if the distribution we imported had an existing default ''stdu'' user, the //new// default user will be ''root'' ! |
| | * It is possible to explicitly specify the requested user each time we start a terminal, but it will be more convenient to specify a default user\\ wsl --distribution Ubuntu_custom --user stdu |
| | * Specify a default user (note: [[https://docs.microsoft.com/en-us/windows/wsl/use-custom-distro#add-wsl-specific-components-like-a-default-user|Add WSL a default user]] also shows how to //create a new user//). We just have to use the root account to add a default user (user ''stdu'' here) to the [[https://docs.microsoft.com/en-us/windows/wsl/wsl-config#user-settings|/etc/wsl.conf]] file |
| | * <code># cat /etc/wsl.conf |
| | cat: /etc/wsl.conf: No such file or directory |
| | |
| | # echo -e "[user]\ndefault=stdu" >> /etc/wsl.conf |
| | |
| | # cat /etc/wsl.conf |
| | [user] |
| | default=stdu</code> |
| | * Restart the Linux installation to take the new settings into account |
| | * ''%%wsl --terminate Ubuntu_custom%%'' |
| | * If you need the ''root'' account later, you will need to use the ''sudo'' command from the new default account |
| | * <code>$ whoami |
| | stdu |
| | stdu@sadira034:~$ sudo su - |
| | [sudo] password for stdu: |
| | root@sadira034:~# whoami |
| | root</code> |
