I would like in my jessie and stretch boxes (one of each, both with
systemd) to mount /tmp on tmpfs instead of a hard drive partition tmp
or /dev/mapper/SOL1-tmp.  I assumed that to do so I could not have
either of those partitions; so I unmounted them and then deleted them
as a partition or as part of a LVM as the case may be.

I then created a created a line in /etc/fstab as follows:
tmpfs	/tmp/	tmpfs	nodev,nosuid,size=20%	0	0.  When I rebooted I
received dependency errors.

In addition to the line above /etc/fstab still had a line
/dev/mapper/SOL1-tmp	/tmp	ext2	defaults	0	2.

However, df shows the first line (tmpfs /tmp etc.), but not the second
(/dev/mapper/SOL1-tmp etc.)

Obviously something is wrong but what?  I know that file
/etc/default/tempfs cannot be used in systemd, but I am at a loss to
know what if anything replaces it in systemd.  Apparently it is not
enough to add the tmpfs /tmp tmpfs etc line in /etc/fstab or run
"systemctl enable tmp.mount".
