Operating system that comes with an uninstaller.
@alexbuzzbee just trash the HDD/SSD
@Mia The "Linux uninstaller" also known as `dd if=/dev/null`.
@alexbuzzbee @Mia and Windows’ is `format C:`
@IslandUsurper @Mia Yeah but that leaves an NTFS or FAT filesystem still on the partition.
@alexbuzzbee @Mia you didn’t say anything about uninstalling the file system. 😝
@alexbuzzbee some installation CDs remove themselves after installation is finished. Technically, the installation media itself counts as an "OS that uninstalls itself"
@alexbuzzbee Oh you mean `rm -rf / --no-preserve-root` ?
