sysinst partitioning failure--need quoting/translation for disktab?

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

Logging this here quickly as I am operating in a remote location.

Installing NetBSD/amd64-7.0_BETA via 'sysinst' bombs out at the
partitioning step on a DELL PowerEdge 1950 w/DELL PERC 5/i as follows:

----------
Could not open /tmp/disktab.PERC 5/i        for writing


sysinst terminated.

To return to the installer, quit this shell by type 'exit' or ^D
-----------

It seems that the disk name derived from the RAID controller contains
an embedded "/" character.  Perhaps such things need translations to
make a reasonable file name?
