the disktab entry for an rz25 is correct in the alpha port. There are
also other models which are similar, but not, "rz25"s, e.g. the "rz25l".
This isn't specific to rz25-family disks.
Looking through a DEC (Digital UNIX) disktab, i see entries for:
rz23
rz23l
rz24
rz24l
rz25
rz25L
rz26
rz26b
rz26l
rz26m
rz28
rz28b
rz28l
As far as i can tell, some of those are just different partition
layouts, or something, but others (in particular, all the 'l' models)
appear to be different actual disks.
