We do this all the time. We have a very minimal root filesystem and aren't
currently using any of the frameworks for building root filesystems, so
everything is done with make. In general, we create tar files for each piece. The
piece that has device nodes has a make file with something like:
all:
fakeroot make fakeroot-package
fakeroot-package:
mkdir -p image
mknod image/dev/null c 1 3
mknod image/dev/random c 1 8
tar -C image -czf image.tgz .
We ran into some issues when we separated running mknod and tar into separate
fakeroot invocations because there is a bug in fakeroot with exporting and
importing its state. Fortunately, doing all of this under a single fakeroot
command works just fine. When we untar the tar files for all of the pieces to
create a root filesystem image and then run mkcramfs to create a CRAMFS image, we
do all commands under a single invocation of fakeroot.
No stage of the build requires running as root.
