Where is it advised to make / 10 GB? Do you have any other
functional parts that get their own partition traditionally
(such as /tmp, /var, /usr) on the / partition?

The installation process should not make the system bigger,
as updating the system usually keeps nearly the same sizes.
An exception is the kernel: Here, a backup of the previous
kernel will be generated.

On a partition / with 10 GB capacity and at least 1 GB free
you should not run into problems. Kernel and modules should
not grow bigger than that.

You could try to mount the partitions via

	# mount -a
	# exit

and bring up the system in multi-user mode, if possible.
You can try to make sure there is sufficient space on the
/ partition to repeat the system and kernel installation

Make sure you read the comment section of /usr/src/Makefile
which gives a very good roadmap of how to properly perform
an update.

If you can provide command output. You can use the program
"script" to make a copy of all terminal input/output to a
