Hi all,
I encountered problems using VMware (release 2) on a diskless
workstation when using netgraph bridging. It appeared that
while /usr/local/etc/rc.d/vmware.sh was setting up the bridge
the NFS mounted partitions became unreachable and the ssytem
was hanging.
The work-around I found was to build a static version of
ngctl and change /usr/local/etc/rc.d to copy this static
version and a file containing the ngctl subcommands to /tmp
which is a MFS filesystem and run the static ngctl from there.
I don't know if this is the preferred way to solve this problem
but for me it works so I thought I'd better share is with
possible other victims of this particular incompatibility between
VMware with bridged Ethernet interfaces and diskless workstations.
Ngctl was built by running 'cc -static *.c -o ngctl' in the ngctl
source directory. Here's the diff to /usr/local/etc/rc.d/vmware.sh:

My /etc/vwmare.ngbridge (in the shared /usr tree) contains:
connect vmnet_bridge: fxp0: link1 lower
connect vmnet_bridge: fxp0: link2 upper
msg fxp0: setautosrc 0

Hope this helps others in the same situation.
