Hello,
I have a small question re/ makefs && gpart:
There is a script src/release/i386/make-memstick.sh to create an image
from a full directory tree; the tree is result of
make installworld DESTDIR=/tree
make installkernel DESTDIR=/tree
the script mainly does:
...
makefs -B little -o label=FreeBSD_Install ${2} ${1}
if [ $? -ne 0 ]; then
echo "makefs failed"
exit 1
fi
rm ${1}/etc/fstab
unit=$(mdconfig -a -t vnode -f ${2})
if [ $? -ne 0 ]; then
echo "mdconfig failed"
exit 1
fi
gpart create -s BSD ${unit}
gpart bootcode -b ${1}/boot/boot ${unit}
gpart add -t freebsd-ufs ${unit}
mdconfig -d -u ${unit}
As you can see, it does makefs first, and after this it creates the
gpart structure in the image (i.e. in its memory file system).
Why is this in this order and where exactly starts the file system
created by makefs?
Thanks
matthias
