File system layout and mount points question

[jaywalker]

I'm not sure if this is the right place to ask, but some passer-by may have answers and maybe more will have opinions.

Two key developments introduced in Cauldron for Mageia 2 seem to bring with them some changes to the content of the root file system. The first is the use of systemd which does not work unless /usr and possibly /var are fully included in / rather than be used as mount points for the usr and var partitions.

The other has come about from hacking on usdisks (presumably) to get cdrom/dvd and floppy handling sorted out and to fix USB memory stick unmounting, This means that /media is now not only emptied on every restart, but stays empty as the new media mount point is in a new (to me) root directory in the path /run/media/USER NAME/...

My questions are:
1. Are we still obliged to maintain a large / for everything other than /home?
2. Is there a likelihood that we can go back to separate usr var and tmp partitions soon?
3. Now that first /mnt and now /media have fallen into disuse, will they be kept?
4. The /dev/fd0 and /dev/cdrom lines still give /media as the mount directory but the devices are nevertheless mounted in /run/media/USER NAME/... Should this be changed or ignored?

Thanks in advance for any answers. All comments are welcome.

UPDATE. A few days ago when I started to formulate these thoughts the bug in removable device mounting had been fixed. It looks like it is back and I will need to investigate further, perhaps re-open https://bugs.mageia.org/show_bug.cgi?id=4643.
