<podman@lists.podman.io>Hi,

on fedora 30 as root
# dnf install dumb-init

let's try podman as normal user
the following command does not work (busybox image)

$ podman run --rm -ti --init --init-path=/bin/dumb-init busybox /bin/sh
standard_init_linux.go:211: exec user process caused "no such file or
directory"

but when using fedora image it works

$ podman run --rm -ti --init --init-path=/bin/dumb-init
registry.fedoraproject.org/fedora-minimal:30 /bin/sh

but when using statically
and as normal user
$ curl -sSL -o ~/.local/bin/dumb-init
https://github.com/Yelp/dumb-init/releases/download/v1.2.2/dumb-init_1.2.2_amd64
$ chmod +x  ~/.local/bin/dumb-init
$ ldd ~/.local/bin/dumb-init
not a dynamic executable
$ podman run --rm -ti --init --init-path=~/.local/bin/dumb-init busybox
/bin/sh

it works fine

so should fedora ship statically linked dumb-init?

If the primary purpose of dumb-init is to be used in containers, then
it needs to be statically-linked; mounting a dynamic binary into a
container is asking for trouble.

I thought we were trying to get catatonit packaged for Fedora as the
intended primary init binary for `podman run --init` but I'm not sure
where those efforts stand.

Thanks,
Matt Heon

Please open a bugzilla on dumb-init. No idea on catatonit
