[Nottingham] I knew I'd forget something last night (filesystems and partitions)

I'll let others more fully comment first.

Brief notes:

I have a prejudice against the workings of XFS and ZFS...

For booting up a root partition, you can have complete freedom by using
for example a 256MByte /boot partition using ext4. (That can be smaller
if not using a initrd, needs to be 512MByte or so for some bloated distros.)

For current SSDs, there's no concern for wear levelling and so there is
no special concerns to favour using F2FS.

The big question is... What features/usage do you need?

Have fun!
