Just an oversight that will be corrected once things stabilize. :)

The last major problem was an incorrect DNS entry for mail.oarcorp.com
that was resolved this morning although it will take time to propagate.
FWIW the change doubled our bandwidth!!

Functionally no, it has not changed.

Long ago, Ian Lance Taylor submitted a nice addition to the Linux port
that has never been adequately addressed.  It used dyanmic loading to
let us use more native Linux functions and avoid name space clashes. He
used it so he could use the TCP/IP stack.  With this support integrated,
it should be possible to access any Linux system call using similar
techniques.  Then you could treat a regular file as a block device.

I should have it deep in my archives and I think Ralf has mentioned
having it himself.  It should be an effective way to enable more
of RTEMS for the UNIX Port.
