A neater df alias is:

alias df='df -hT -x tmpfs -x cifs -x rootfs | grep -vE

Tho I would always suggest not introducing a pipe and grep here due to
the arguments being given then applying to grep not the df command itself.

We've shipped a modified df alias by default for years in
Mageia/Mandriva to skip supermount mounts (long since dead I guess).

As for the output from "mount" itself, I would suggest this should
remain as it is. As a sysadmin I want to see the mounts, not hide them
because they look ugly.

I'm OK with abusing/aliasing df as it's a more user friendly command.
