Bug#1061280: sysvinit crashes podman container on install

[Mark Hindley]

Sam,

Thanks for this.

A quick look at sysvinit-core postinst reveals:

restart=yes

if ischroot --default-true ; then
	restart=no
fi
if [ -n "${DPKG_ROOT:-}" ]; then
	restart=no
fi

# If systemd is running, don't restart init or doing any initctl
# migration.
if [ -d "$DPKG_ROOT/run/systemd/system" ]; then
	restart=no
fi
if [ "$(uname -s)" = "GNU" ]; then
	restart=no
fi

if [ "$restart" = "yes" ]; then
	do_restart
else
	echo "Not restarting sysvinit"
fi

My initial thought is that restart should really be 'no' if it is a new
sysvinit-core installation. The attached patch fixes sysvinit-core installation
within a podman container for me. I need to do more testing to check that it
doesn't cause breakage elsewhere.

Can you confirm?

Thanks

Mark
