mount for external filesystem support
 

Is there any version of mount that supports external file systems? If so, where can I get it? I would like to use siefs file system (based on FUSE) with mount utility but my mount (version 2.11x) doesn't support it.
Thanks in advance.

What exactly do you mean by external file systems? If you explicitly give the fstype (via -t option or in fstab) mount searches for a mount.fstype command
Have you read this: http://mirror01.users.i.com.ua/~dmitry_z/siefs/ ?

Yes, I have read this. I mean exactly siefs in my question. On the project web page, it is written:

If you have old mount version that doesn't support external filesystem types, a command for mounting will be
fusermount /mnt/mobile siefs /dev/ttyS0 [options]

My mount doesn't work with siefs so I use fusermount command, but I would like to use mount instead. Is it possible in some way?

I have 2.11z, I never used siefs, but according to manpage it should work as long as a /sbin/mount.siefs exists and type is explicitly given.
