But then there is the real danger that I have no DECwindows at all.

No, neither.

Current as of patch-cutoff day.  :-|

An XP1000 is not suited for running DECwindows?

OK, upgrade to avoid the free-space drift.  OK.  But there is still the 
DECwindows problem.

I have 9 GB on the system disk, with 4 free.  Just upgraded another disk 
from 18 to 36 today.  Not THAT small.

2 GB.

My plan is to skip Itanium and go directly to VMS on x86.  :-)

Will do.
