There's a pending patch from Changqing, which also handles /var/tmp.
The title is: [OE-core] [PATCH] VOLATILE_TMP_DIR: Extend to specify the persistence of /var/tmp

I think we'd better handle that patch first because you may need to change to the way you used in your second patch to handle this /var/tmp link.

Regards,
Qi

The base-files recipe provides /var/tmp -> /var/volatile/tmp symlink
which is in conflict with systemd upstream tmpfiles.d/tmp.conf which
defines it as a directory (or subvolume on btrfs).

This generates following error in journal:

   Jul 03 15:37:21 qemux86-64 systemd-tmpfiles[158]: "/var/tmp" already exists 
and is not a directory.

Mitigate the issue by defining /var/tmp as symlink corresponding to
the one created by base-files.
