Well I think ~x86 is generally usable, but you do have to be a bit
more cautious.  For example, I don't mind --sync every day, but I tend
to delay any updates that involve portage, baselayout, or other
lowlevel system packages until Friday nights, after making a backup,
so I have the whole weekend to pickup the pieces if something should
break.

And today I think if you encounter anything stable that depends on a
~x86 package, it is a bug, and should be filed as such.

The job of depscan.sh is to rebuild this file.  But if the file exists
and is newer than the configuration in /etc, it will not do anything,
even it if deptree is empty.  So delete deptree, and run depscan.sh
again with the --debug option.  You should see a bit more happen.

A badly timed Ctrl-alt-del or reboot could be the culprit.  There is a
window of opportunity while depscan is running that if it is aborted,
will leave you with an empty file.
