petardfs is a FUSE filesystem designed to hoist your applications with errors. With no configuration, petardfs takes a base filesystem and exposes it through FUSE.
An XML configuration file is used to tell petardfs which files to report errors for and what error code to use. For example, foo.txt can have an EIO error at bytes 34 to 37.
There is explicit support for errors such as EAGAIN and EINTR, where petardfs will only report such transient errors a nominated number of times. This is handy for testing applications that support such I/O conditions gracefully.
