James, ALErs -

Thanks for the lead.

This was the right idea (Linux creates any essential '/tmp/' files at 
boot), but I still didn't start X11 successfully in RH-7.3. What _did_ get 
me home was pre-creating all the /tmp/* subdirectories by the following 
ugly, round-about hack:

# mkdir /get_tmp
# telinit 1
sh # (cd /usr ; tar cf - ./tmp ) | (cd /get_tmp ; tar xvf - )
sh # cd /get_tmp
sh # find ./tmp ! -type d -print > ./tmplist
sh # rm -f `cat ./tmplist`
sh # cd /
sh # rm ./tmp
sh # mv /get_tmp/tmp .
sh # shutdown -h now

(Cycle power for calm, quick and orderly reboot. #8-)

Take out the trash:
# rm -rf /get_tmp /usr/tmp

NOTE1: '/usr' and '/' were different partitions so I used 'tar' to
transplant the ./tmp branch but 'mv' to move it down by one directory in 
the same partion.  

NOTE2: The song-and-dance through the dummy '/get_tmp' branch just
minimized the number of operations I did without a viable './tmp': you
could probably dispense with it. If I planned doing this again #8-) I
might try fewer steps, but I hoped caution would minimize further digital
self-amputations:

Cheers.
