 Thanks!  I thought ntpd might be useful for keeping the time sync'd,
 but I didn't realize how much memory it's eating.  And probably
 ntpdate is sufficient if I just want to keep the system time in sync
 with Internet time (?).  I'll stop running ntpd now.
 It appears that right now at least the 9.2 kernel may in fact be
 stable on this machine.  That makes me have faith in Michael van
 Elst's suggestion that the freeze during install could be simply due
 to a lack of memory.
 I'll be experimenting with a few solutions going forward:
   - Getting a memory card for my TT030 that is >16MB and runs stable.
   - Cross-building netbsd for atari with -Os and using the sysinst.fs
 and ataritt kernel that it generates for the install.  I can also
 remove some things from my build of the ataritt kernel, which could
 It might make sense to use this PR to track any potential changes that
 could help get 9.2 to install successfully on a 16MB TT030.  The most
 common RAM board for the TT (the Atari branded board) will do 16MB
 max, and in my experience many >16MB RAM boards don't run stable with
