Yes, but upgrading/installing is done as root anyway, and I think
the problem came from /bin/sh and other tools depends on shared
objects in the packages itself. (If the nonhonor of LD_LIBRARY_PATH
is the only thing, you could change ld-linux.so.1 to be able to go
temporary into some debian_is_updating state. David, you have the
source. -- Just kidding.)
The other problem are running/starting programs during the (short)
exchange time independend from the upgrade process, like cron, incomming
telnets or other work on this machine. Now I am rather convinced we
should force a single user mode during upgrading/installing essential
parts of the system (ld.so, libc, shared object needed by bash, perl(?)).
