Sometimes when you do an incremental build, you run into some fluff that kills your build:

==== cpio archives build errors (DEBUG) ====

Failed to create generic kernel archive:	200550 blocks
cpiotranslate: kernel/misc/amd64/sysinit: no packaging info
cpiotranslate: kernel/misc/sysinit: no packaging info

And everyone is supposed to know how to handle these:

[th199096@aus-build-x86 mms]> ls -al proto/root_i386/kernel/misc/amd64/sysinit
-rwxr-xr-x   1 th199096 staff       4200 Sep 25 21:22 proto/root_i386/kernel/misc/amd64/sysinit
[th199096@aus-build-x86 mms]> rm proto/root_i386/kernel/misc/amd64/sysinit proto/root_i386/kernel/misc/sysinit
[th199096@aus-build-x86 mms]> `which nightly` -in nightly.env

Hey, what do you know, Ken Erickson did have a Flag Day for those who maintain private copies of bfu; Heads up for everyone else], but it still does not mention cleaning up the turd on your own.

After all, everyone knows how to deal with these turds.
