Kali Live / Files in tmp folder

Hi,

I'm hoping someone can help clarify

I installed the latest kali on a bootable usb, when I looked at the tmp folder, i see the following strange files:


ssh-xxxxx-xxx
tmp/systemd-private-xxxxxxxxxxxxxxxxxxxxxx-colord.service-GvYXpj
/tmp/systemd-private-xxxxxxxxxxxxxxxxxxxx-haveged.service-Atl91g
/tmp/systemd-private-xxxxxxxxxxxxxxxxxxxx-iio-sensor-proxy.service-nqtKRe
/tmp/systemd-private-xxxxxxxxxxxxxxxxxxxxxx-ModemManager.service-Ndocuh
/tmp/systemd-private-xxxxxxxxxxxxxxxxxxxxxxxx-systemd-logind.service-wkCofg
/tmp/systemd-private-xxxxxxxxxxxxxxxxxxxxxxxxx-upower.service-t0TSnf



What are these files and should I be worried? i'm concerned that since its a live usb, these files will always appear at each boot. I did a search on google & it says I should check if my ssh is running, the systemd files are normal, and I can stop any sshd services, but I can't work out why sshd would be running in the first place? or why they are all saved in tmp folder, I did a verification of the iso download and the hashes match so I dnt think its a bad copy
