Question: According to Wikipedia

extra disks should not be mounted in `/mnt/` according to the first link, but doesn't seams so according to the second link.

Both say thought that they shouldn't be in `/media`.

**Question**

So where should extra permanent disks be mounted?

Answer: 
Extra disks are typically mounted in a directory called `/media/*something*` where the *something* reflects the mounted device, e.g. `/media/cdrom0` for the first CD-ROM device. This convention is widely followed under Linux for removable devices, and often but not always for permanent devices.

The FHS forbids distributions from using directories under `/mnt` because some administrators use `/mnt` itself as a mount point for temporary mounts. If you're the administrator, you can do what you like; just don't use `/mnt` itself as a mount point if you create directories under it.

Many places have their own convention. Some automounters have their own directory or directories (configured through `/etc/fstab` and `/etc/auto.*`); `/amnt` or `/auto` are typical names. Network mounts are often put under `/net/$machine_name`. Some places just use whatever went through the administrator's mind: `/data`, `/local`, `/scratch`, …

Of course, filesystems that have a specific place in the directory structure should be mounted there. For example, the mail partition is normally mounted directly on `/var/mail` or `/var/spool/mail`. If your home directories are spread between several disks, it's typical to mount them underneath `/home`, e.g. `~alice` = `/home/disk0/alice` and `~bill` = `/home/disk1/bill` and so on, if you want to expose the different disks in home directories. If you don't, then mount the home partitions wherever you like and create symbolic links or automounts in `/home`.
SuSE had /srv as generic mountpoint for server-related stuff.

/var/lib/yourapplication seems to be a standard, too.

Since I use the automounter with fixed entries for these things, I tend to use /automnt.

The media automounted by UDEV (/media) is being redirected through CLAMFS (for virus scanning) to /extern on my workstation.

So short - there is no real standard - it`s up to you.
