I think the somewhat unpopular part is to recommend *against* using LVM
for the OS partitions, voting instead to KISS, and only use LVM / Btrfs
/ ZFS for the "data" part. Some people actually think LVM should be used
everywhere.
And for clarity's sake, I'm not suggesting a literal partition /os and
/data, simply that there are areas of the filesystem used to store
operating system stuff (EG: /bin, /boot, /usr), and areas used to store
data (EG: /home, /var, /tmp), etc.
Keep the OS stuff as simple as possible, RAID1 against bare partitions,
etc. because when things go south, the last thing you want is *another*
thing to worry about.
Keep the data part such that you can grow as needed without (much)
downtime. EG: LVM+XFS, ZFS, etc. (And please verify your backups regularly)
