Hi,
I am trying to clear /tmp files on boot to see if it gives me more space on /
I have found this: https://forums.opensuse.org/showthread.php/412640-Clear-Temp-Files-at-Boot
However, in Yast>Cron is empty. It doesn’t look like the screen shot.
I know it is old, but I didn’t want to use Console, as I am easily confused.
Is there another way to clear /tmp files at boot using GUI?
Thank you.
For cleaning /tmp and /var/tmp at boot:
When there is not already a file /etc/tmpfiles.d/tmp.conf create it as a copy
cp /usr/lib/tmpfiles.d/tmp.conf /etc/tmpfiles.d/tmp.conf
Then change the lines
# Clear tmp directories separately, to make them easier to override
# SUSE policy: we don't clean those directories
d /tmp 1777 root root -
d /var/tmp 1777 root root -
into
# Clear tmp directories separately, to make them easier to override
# My policy: empty /tmp en /var/tmp on boot.
D! /tmp 1777 root root 1d
D! /var/tmp 1777 root root 1d
See
man 5 tmpfiles.d
================================
For making /tmp a tmpfs:
Add an entry into /etc/fstab
tmpfs /tmp tmpfs size=25%,uid=root,gid=root,mode=1777 0 0
See
man 8 mount
specialy the section: Mount options for tmpfs.
Before mounting this file system for the first time (either by command, or by reboot) you should clean the present /tmp directory as good as possible. Existing contents will still occupy disk space when you mount a file system over it.
Sorry for the delay. I am in the middle of an ongoing family crisis. Some information to help with the root partition full problem:

I am considering copying my home partition to an external hard drive, then changing the partition sizes and reinstalling Leap 42.3. It may seem like a lot and long winded, but I do not feel focussed enough to attempt commands.
From my brief look at other posts is this something to do with btrfs? Can I save myself this problem in the future by using a different type of partition? I am really looking for an easy solution, that is also one which I sort of understand.
A big thank you for taking the time to type in all those instructions, but I can’t focus. If I just copy and paste them will that work? I am loathed to do that, as I like to sort of understand what I am doing. If I am going to behave like a robot, I might as well use windoze and phone a helpline when it goes wrong 
Thanks for bearing with me.
