I agree, this time it seems to be an emulation problem. I'll try on my real lisa this weekend
but I have an Xprofile and not a real lisa hdd so it may also fail for a similar reason.

also, there may be problem with the install procedure since it creates a pa device instead of
a p0a device ($physical is not set in shell) so maybe the filesystem is not where it should
be (In the past, I had a similar problem under linux, I created filesystem on the raw device and not the partition...).
