Re: Separate tmp-dir for every user?

If you're using tmpfs, then my understanding is that the files are

maintain the per-user temp directories between reboots? Do you create
them all and save an image of the ramdisk, which is then loaded into
the system on every boot-up? Is there a script in init.d somewhere
that does that?




I'd strongly advise against ever using tmpfs for storage on a shared hosting server. This means any user can easily DoS your system by filling up the tmp directory and thus your RAM; if you store the /tmp dir on a regular filesystem files will still be stored in memory by the filesystem cache if enough RAM is available, but that RAM can also be used for other processes when needed.
