Multipath on Slackware

Hi

I am trying to get multipath working on Slackware 13.37 with device
mapper on an Intel MFSYS25.  After a standard install I have compiled
and installed multipath-tools.

The server has 2 'disks' allocated to it.  I have created
/etc/multipath.conf and populated it with entries for the two disks:
'system' and 'data'.  'system' is where / mounts from.  On reboot the
path for 'data' is created as /dev/mapper/data and mounts, so the
multipath is working fine.  The problem is the path for the root disk.

I have created a initrd with the multipath modules as well as the
multipath binaries and udev rules.

I suspect that the path is not being created before the disk is
accessed (as /dev/sda).  I assume the paths are not being created by
the init in the initrd.

As a side note I have got it working properly in Debian and even tried
to use the Debian initrd as a base in Slackware but without success.

Any pointers will be appreciated.
