Tini is the simplest init you could think of.

All Tini does is spawn a single child (Tini is meant to be run in a
container), and wait for it to exit all the while reaping zombies and
performing signal forwarding.

%description static
Tini is the simplest init you could think of.

All Tini does is spawn a single child (Tini is meant to be run in a
container), and wait for it to exit all the while reaping zombies and
performing signal forwarding.

This package contains statically linked tini. The dynamically linked
tini uses only libc, so using statically linked program makes only
sense if you do not use libc in your container.
