Using the shared /tmp directory is known to have lead to many security vulnerabilities when predictable filenames have been used. And randomly generated names aren't really nice looking.I am thinking that maybe it would be better to use a per user temporary directory instead. Many applications will use the TMPDIR environment variable in order to decide where temporary files goes.On login I could simply set TMPDIR=/temp/$USER where /temp would then have to contain a directory for each user with that directory being writable to that user and nobody else.But in that case I would still like /temp to be a tmpfs mountpoint, which means that the subdirectories would not exist after a reboot and need to be recreated somehow.Is there any (de-facto) standard for how to create a tmpfs with per user subdirectories? Or would I have to come up with my own non-standard tools to dynamically generate such directories?
