Re: Separate tmp-dir for every user?

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

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.
