Aren't MDMFS backed filesystems of static size? And haven't they to be created first before they can be used? Using TMPFS seems toi be a more convenient way to me - dynamical (?), using a fstab entry for convenience. > > However, if you always want to use tmpfs instead of stable storage, > please do not.

I treat /tmp as it is: temporary. No one should change the default setting. Well, SSDs become more and more popular, even for heavy duty servers. Still facing the waer-off problemacy with NAND flash memory, I'd would feel better have the main memory used by the volatile filesystems like /var/run and /tmp which get rewritten quite often.
