Once you have your system ready to be packaged:
- use makefs(8) to create the filesystem image:
makefs <image file> <image root directory>
- note down the resulting file system image file, then compile a kernel
options MEMORY_DISK_IS_ROOT # root on memory disk
options MEMORY_DISK_ROOT_SIZE=40000 # size of fs image in blocks
- mdsetimage(8) to embed the image in the resulting kernel:
mdsetimage <kernel> <image file>
Boot with the resulting <kernel>. If your host system is not NetBSD,
build these tools via build.sh.
