OT-ish: Best TMPFS solution on Debian

[Glenn Park]

Hello,

I'm new to Debian and am trying to understand the Right way to make
the default Debian amavis package (installed with aptitude) have its
tmp directory in-memory.

Is it acceptable to just do this after the installation has completed?

service amavis stop
rm -rf /var/lib/amavis/tmp/
ln -s /dev/shm /var/lib/amavis/tmp
service amavis start

Thank you!
