Yes and no. The main version is forked from ubuntu, but there is also LMDE which is debian based.

A good way to keep this easy for yourself is to keep the files you actually care about like pictures, game saves, documents, etc all on a separate partition. It makes it very easy to make a backup for distro hopping.

You can nuke your OS as many times as you like, and everything will be exactly in the same place.

Pretty neat, but probably not something I’d buy
