tmperamental - avoid writing to /tmp
Contents
Description
tmperamental uses a preloaded library that intercepts filesystem writes, and causes loud failures when
writes are attempted on /tmp/*
The idea here is by setting TMPDIR and friends, it catches programs in the act of not respecting such
env-vars.
Environment
If TMPDIR is unset, tmperamental will set it automatically to $HOME/tmp.
tmperamental uses LD_PRELOAD to load a custom library libtmperamental.so that intercepts library calls.
Limitations
tmperamental only catches writes to /tmp at shared object library calls using the standard libc interface. A statically-compiled program that makes system calls directly will be able to write to /tmp without being intercepted. tmperamental 1.2 March 2020 TMPERAMENTAL(1)

Usage
Prefix the command you want to run with tmperamental and it should cause it to abort if it ever tries to
write anywhere within /tmp. This is pretty brutal, so you probably only want to use it for testing.
