No, but IIRC the tmpfs filesystem created and mounted on /tmp is 50%

Seems extreme. How many temporary files are that big?
/tmp is system-wide writable, i.e. any arbitrary users and any arbitrary
process can create an arbitrary number of files in /tmp.
As /tmp had been the traditional unlimited sink for temporary files,
many tools create temporary files of arbitrary size in /tmp.
These tools will occasionally fail to work with TmpOnTmpfs and may cause
system malfunctions, esp. on small RAM systems.
