I believe there may be a misunderstanding about the meaning of the Linux partitions.
The partitions /dev and /run are temporary file systems.. According to this Web page (which is clearer than Wikipedia, IMHO),
A temporary file system uses memory to simulate a traditional disk partition. Normal file system writes are scheduled to be written to disk along with access control information, but the files actually reside in memory only.
A good candidate for a tmpfs is a partition that will have many small files that will be accessed often, e.g. /tmp. This will considerably speed up their access time. Tmpfs files and directories are NOT saved when the system shuts down.
The only two real partitions you have are /dev/sda8 and /dev/sda7. The fact that you have two partitions is indeed quite positive for you: for instance, you can install a new version of Ubuntu on /dev/sda8, without any fear of losing your data on /dev/sda7.
However, there are two issues with your partitions (and, BTW, where is your swap partition?). The first one is that you are hosting your system on logical partitions, while it is preferable,though by no means necessary, to do so on primary partitions. The Linux Foundation recommends doing this, because data recovery in case of hardware failure is so much easier. The second issue is that the two partitions are incorrectly proportioned, the one hosting your system, /dev/sda8 being much larger than necessary. Out of a total of 214 GB, 30 GB for the system are plenty, the rest might very well be left to your /home filesystem.
