I noticed that when you delete a virtual machine with its virtual disk, the disk space does not come back.
What should you do to recover disk space when you delete a virtual machine?
I thought of using bleachbit as root to delete temporary files, but this one refuses to launch. This seems to be related to the fact that the root account has a particular function on the Purism. Sudo -i works, but su - no. I understand that for security reasons access to full root is disabled, but is there a way to re-enable it to clean with bleachbit root? Or another way is better ?
