Hi,
Trying to stuff in an MFS_IMAGE into a debug kernel does not work in -current. kern.post.mk tries
to put the MFS_IMAGE in ${KERNEL_KO} when building ${FULLKERNEL} - but ${KERNEL_KO} has not been
created at that point.
The error message I get is:
linking kernel.debug
text data bss dec hex filename
3540430 4532668 149800 8222898 7d78b2 kernel.debug
strings: 'kernel': No such file
rm: kernel: No such file or directory
*** Error code 1
The following patch against version 1.98 of kern.post.mk fixes the problem:
