| * This is an indirect way of reclaiming the unused space of a Linux installation, i.e the size of the ''ext4.vhdx'' file after importing can be smaller than the size of the originally exported ''ext4.vhdx'' file. | * This is an indirect way of reclaiming the unused space of a Linux installation, i.e the size of the ''ext4.vhdx'' file after importing can be smaller than the size of the originally exported ''ext4.vhdx'' file. | ||
| + | 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> | ||
