What are /net and /srv and /misc for?

IFAIK, this is traditionally where global NFS mounts would go.  E.g., 
mount machine2's /opt/foo on /net/machine2/opt/foo.  Usually, you'd back 
these up on the local machine (unless you are doing networked backups 
using NFS mounts.

In the future, global server files will go in /srv.  So /var/www will 
become /srv/www, etc.  /var will be reserved for files that need to be 
writable by the running system--locks, pid files, spools, etc.

/misc is for dynamic mounts (what autofs does), so it should not be 
backed up unless you know you want to.

Right.  And /selinux and /media and /mnt and /tmp.  And several of the 
directories under /var.

See other notes in the thread.
