arla on FreeBSD 4.0 + Linuxulator anyone?

Yep, Acoread{3,4} seems to work fine for me under the latest arla too.

I've spent some more time playing with WP for linux, on my 4.0-RELEASE
box at work, running arla 0.33.1. I still can't open/save files from
AFS. truss'ing Wordperfect turned up the following:

--- Saving to /tmp (non-AFS) -----------------------------------------
syscall linux_open("/tmp/TestDoc",514,0666)
        errno -2 'No such file or directory'
syscall linux_open("/tmp/TestDoc",66,0666)
        returns 30 (0x1e)
syscall linux_fcntl(0x1e,0x5,0xbfbf8564)
        returns 0 (0x0)                                  <-- Succeedes
syscall linux_fcntl(0x1e,0x6,0xbfbf8594)
        returns 0 (0x0)                                  <-- Succeedes
syscall linux_newfstat(30,0x87b9b24)
        returns 0 (0x0)
syscall linux_fcntl(0x1e,0x2,0x1)
        returns 0 (0x0)                                  <-- Succeedes
----------------------------------------------------------------------

--- Saving to my home dir (AFS) --------------------------------------
nux_open("/afs/eng.utah.edu/home/ricci/TestDoc",514,0666)
        errno -2 'No such file or directory'
syscall linux_open("/afs/eng.utah.edu/home/ricci/TestDoc",66,0666)
        returns 28 (0x1c)
syscall linux_fcntl(0x1c,0x5,0xbfbf8564)
        errno -95 'Operation not supported'                  <-- Fails
syscall linux_newfstat(27,0x87b9b24)
        returns 0 (0x0)
syscall close(27)
        returns 0 (0x0)
syscall linux_open("/afs/eng.utah.edu/home/ricci/TestDoc",2,0666)
        returns 27 (0x1b)
syscall linux_fcntl(0x1b,0x5,0xbfbf85c4)
        errno -95 'Operation not supported'                  <-- Fails
----------------------------------------------------------------------

This ends up creating an empty file in my home directory, and gives
the error message "An error occured opening the file ...". Seems that
it's the failing fnctl that's causing WP to complain. It seems the
failure only happens when arla and the linuxulator are combined,
because I can save to AFS space just fine with arla under Linux.
