I will never understand why people just keep making arbitrary di-
rectories like /data off of /, when there is a very clear  speci-
fication which says that /var/opt is for third party data, but it
is very upsetting when I see /data or /srv, or anything else  ar-
bitrary like that.

It  would  be really swell if this were /var/opt by default, like
the filesystem(5) manual page says. That  is  SVR4  and  a  Linux
Standards Base filesystem standard. There is absolutely no reason
whatsoever to re-invent the wheel.

I agree. Following the standard makes sense. When installing packaged software there is an expectation that the system will have enough space in a standard location (e.g. /var/spool/xxx, /var/lib/yyy, /var/www, /usr/share, and indeed /opt, to name a few). If a database is expected to be large, one can allocate appropriately on the correct filesystem location. With dynamic volumes (LVM, etc.), it is also possible to re-provision more space later. It's not about allocating a huge disk and hoping for the best. It's about planning and thinking ahead as far as I'm concerned.

Don't forget that unlike on a physical system, in a virtualised environment "disks" can be thin provisioned.
