   Bug#1032610: reliably composable initram

   I would caution against that and rather only add the quick and easy bit:   
      
   1) Fixing the regression and adding autopkgtest is adds little code yet   
   solves the hassle for any *manual* workflow that once worked.   
      
   2) Actually parsing such archives is way more complicated - and for   
   what? Unless   
   unmkinitramfs was aiming for perfect bug-compatibility with kernel code   
   it would   
   always harbor potential for dangerously misleading output.   
      
   > whether 3cpio supports multiple compressed parts   
      
   No. Looks like it shuts down even if current decompression stopped short   
   of EOF:

   (Still good, insofar it means my suggested unconditional padding does   
   not make it crash.)
