 Isn't there something calles "efslook"? I found it mentioned
somewhere in the SGI FAQs. Probably does not really "mount"
the EFS volumes, but you should be able to read them.

  Definitely. Do away with EFS as soon as manageable.

Hey, I'd love to switch to iso9660.  Unfortunately, how do we read all
the CDs that have already been generated?  For example all the free
source code that has been generated on the Developer's Toolbox and
stuff.  Also, after a linux kernel has been booted, it would be nice
to mount SGI file systems.

Adding 9660 does not require us to remove EFS.

I think the issue may have more to do with PROMs and sash and stuff like that
than the OS proper.

Re: EFS and XFS file systems support

[Larry McVoy]

At this point, since we are moving away from EFS, it is possible that we would 
be willing to donate a version of the EFS code to Linux.  I can probably get 
that cleared.  But someone else would have to do the port, I'm too busy.
If you find someone to do the port, let me know.

Assuming it's all cleared with everyone, and we get a source
repository somewhere to play with, I might give it a shot.  Does
anyone know if the efslook stuff is GPL'd?

If you can get it cleared, I'll do the port.

Initially, I'll port it to my system at home and create an EFS
filesystem on a Zip drive and see if I can read it here in the office.

If that all works, then I'll pass my source to one of the other guys
who actually has a linux SGI box.

EFS and XFS file systems support

[Christopher W. Carlson]

I understand that the EFS and XFS file systems are proprietary to
SGI.  I don't really understand why SGI would care if the EFS file
system were divulged but I can understand the XFS file system.

What I wanted to suggest is that SGI provide a library (.a file) that
can be linked with Linux to provide EFS and XFS file support.  If
necessary, we could charge some nominal fee and require some kind of
non-disclosure or promise that the objects won't be reverse engineered
or something.

As a minimum, provide these drivers only to employees.  It would sure
make development easier if we could mount SGI file systems.  My
biggest reason for wanting them supported is to access SGI CD ROMs.

Anyway, just thought I'd add my $.02.
