On FC6 I have; samba-{,client-,common-}-3.0.23c. mount.cifs is version
1.10 (!) and cifs kernel module is version 1.45.

FC6 seems to be some way away from where mkfifo will work, which means
RHEL4 will be even less likely to be able to do this.

Yes, unix extensions is enabled and I mount with
'mount.cifs //localhost/test /mnt/test -o setuids,user=cifs' on my test
system.

I may have to try building samba trunk to see if I can get this working.

Thanks,
