Does OCFS2 support mmap well enough now to allow dselect/apt/etc to
work? When I tried it last time (~18 months ago), I couldn't use it as a
root filesystem for this reason.

ClusterNFS has a really nifty feature that allowed you to name a file
with the MAC or IP address encoded into the filename, which allows
different nodes to see different versions of the files, eg something
like /etc/hostname$192.168.2.7$

Do any of the clustered filesystems you mentioned have that or similar
features?

Thanks
