 Normally you don't ever
 need to think about rebasing on x86_64.  The 
 perpetual postinstall script
 /etc/postinstall/0p_000_autorebase.dash 
 should handle everything without any manual
 intervention.  You might try 
 running that
 script (and the rebaselst script that it calls) line by 
 line (preferably in a dash shell started
 directly from Windows, with no 
 other Cygwin
 processes running) to see if you can figure out what's
  going wrong.

Looks about the same to me, and all the /var/cache/rebase/...
files are basically empty, FWIW, but I could be following
the rebaselst script incorrectly.


$ cat 0p_000_autorebase.dash
#!/bin/dash
export PATH=/bin
b=/var/cache/rebase
if [ -e ${b}/peflags ] ; then
    noaslr=--noaslr
    peflags=peflags
    rm -f ${b}/peflags
else
    noaslr=''
    peflags=''
fi
if [ ! -e ${b}/fullrebase.done ] ; then
    rebase-trigger fullrebase
    rebaselst --rebuild update --cleardb $noaslr rebase $peflags
    mv ${b}/fullrebase ${b}/fullrebase.done
else
    rebaselst update $noaslr rebase $peflags
fi


$ b=/var/cache/rebase
$ ls ${b}/pe*
ls: cannot access '/var/cache/rebase/pe*': No such file or directory
$ ls ${b}/fullrebase.done
/var/cache/rebase/fullrebase.done
$ rebase-trigger fullrebase
Note: _autorebase will do a full rebase the next time setup is run.
