Several obvious reasons that this looks ju= st wrong. (Then again, so is yours in one case.)</div><div style=3D"font-fam= ily:tahoma,sans-serif;font-size:small" class=3D"gmail_default">1. "mergemast= er -p" MUST be run before you build the kernel.

While mergemaster(8) is still in the system, you really should be us= ing etcupdate(8). You also need to understand how a three-way merge is done a= nd that you often need to edit the merged file when first running it.&= nbsp; It's pretty simple to run and rarely is needed after the first run, bu= t it is critical to do this for /etc files that you have modified. It's gene= rally just picking which of the two (original/yours) you want in the final f= ile. The big win with etcupdate(8) is that it only needs to be run once for m= odified files in almost all cases.</div><div style=3D"font-family:tahoma,san= s-serif;font-size:small" class=3D"gmail_default">3. Where is "make check-old= " and the other tests to get rid of old files. Leaving these around can lead= to serious issues.</div><div style=3D"font-family:tahoma,sans-serif;font-si= ze:small" class=3D"gmail_default">4.
