This is a > rewrite of [initrs][initrs] in C, because we found that it is not possible to > statically compile Rust binaries without using musl. That was, in turn, a > reimplementation of other container inits like `tini` and `dumb-init`. > > The reason for re-implementing `docker-init` is because it appears as though > all of the other implementations do not handle signals as correctly as they > should. In particular, they all appear to make use of `sigwait(2)` (`tini` does > a `sigtimedwait(2)` for an interval and then will do a `waitpid(2)` even if it > didn't detect a `SIGCHLD`). `catatonit` uses `signalfd(2)`, which [has its own > warts][signalfd-broken], but the improvements over `sigwait(2)` are significant > in terms of stability. Ideally we would just write a patch for the other > projects to use `signalfd(2)` rather than creating a new project, but after > some time spent looking at `tini` and `dumb-init` we felt that such patches > would be closer to full rewrites. > > In addition, the purpose of `catatonit` is to only support the key usage by > `docker-init` which is `/dev/init -- <your program>`. With few exceptions, no > other features will be added. > > Co-maintainers welcome! catatonit is already available in Debian. Cheers, Vincent
