Re: Where should users have their temp files?

A better solution would be if applications always opened files in /tmp with O_CREAT | O_EXCL. tmpfile(3) does this but the file is always 644. I think there should be a tmpfilem(mode_t) where the mode could be specified. I was forced to implement my own tmpfile(3) from tmpnam(3) to fix similiar

Where should users have their temp files?

There are some nasty attacks with links and symlinks in temp directories (see bugtraq for an extended list). Some programs solve this by putting temp files in home directories. This is clearly suboptimal (networked home directory, quotas, ...). /tmp and /var/tmp are there for a good reason. One
