LynxOS documentation say that uses a "Unix-like" file system . It says you can mount devices as file system, but doesn't state which are supported (e.g. EXT3, EXT4, etc).

According to this article as well as this one, it supports the following:

  • Lynx Fast File system
  • Network File System (NFS)
  • RAM disk file system

A couple follow up questions: - Is Lynx Fast file system proprietary? I'm guessing from the name that it is. - Is a RAM disk really a file system? Wikipedia gives the impression that you can put a variety of file systems on a RAM disk. – TylerS Nov 1 '13 at 18:53
@TylerS As for the RAM disk File system, I have no idea. For the Lynx Fast File system, I believe it's proprietary; the only thing I ever heard about it was that it was used in the space program. – Moses Nov 1 '13 at 19:34
