I don't think so.  See the current /etc/default/rcS below.  It
is also the version almost from the beginning (according to etckeeper),
although I might well have modified it just before installing etckeeper.

No.

Here it is:

#
# /etc/default/rcS
#
# Default settings for the scripts in /etc/rcS.d/
#
# For information about these variables see the rcS(5) manual page.
#
# This file belongs to the "initscripts" package.

# delete files in /tmp during boot older than x days.
# '0' means always, -1 or 'infinite' disables the feature
TMPTIME=-1

# spawn sulogin during boot, continue normal boot if not used in 30 seconds
#SULOGIN=no

# do not allow users to log in until the boot has completed
#DELAYLOGIN=no

# be more verbose during the boot process
#VERBOSE=no

# automatically repair filesystems with inconsistencies during boot
#FSCKFIX=no

Thank you.  That seems reasonable.

That will stop any tmp cleaning, which I don't like, but is a separate
issue from getting rid of tmpfs-on-/tmp.
