gordie692; Hey
Our philosophy: The only dumb question here is the one that you do not ask
could I also use it as a daily OS for everything else
Sure you can - IF you can deal with some maybes on breakage, After all, 21.10 is in the development stage.
Might I suggest that you dual boot - keeping your stable system alive as a backup.
testing and bug reporting is highly encouraged
but I suggest you read at least https://wiki.ubuntu.com/Ubiquity/Testing and maybe https://wiki.ubuntu.com/Installer/Development; those are helpful for how to do the testing and debugging
http://iso.qa.ubuntu.com/ <- report the tests you did
ubuntu
we are all in this together
