Add a Debian init.d script for mptcpd for the case where start of
mptcpd through systemd is not available or undesirable.

The etc/init.d/mptcpd script generated by this change is installed even when systemd is detected by the configure script. I'm not sure that is desirable.

I don't yet know if other platforms such as Fedora support this Debian style init.d script.

Yeah, that doesn't seem good - but I don't know how packagers usually handle installation of sysv-init vs systemd scripts

If I'm not mistaken, you can install both the init.d script and systemd service. If you use systemd and there is a service, the init.d script will be ignored I guess. e.g. for iwd: https://salsa.debian.org/debian/iwd/-/commit/65a0232b9715d9002d69d55b217ae6e3f3c75ffb

If it eases stuff, only having the file in the tarball and not installing it by default (or only with a configure option) would help packagers.
If the init.d script you have is Debian-specific, we can add it in the Debian package directly and not maintain it here.

init.d: Check permissions on mptcpd init.d script.

Exempt init.d/mptcpd script from installcheck.

The $sysconfdir/init.d/mptcpd script does not support --help and
--version command line options.  Exempt it from the Automake generated
installcheck.

Setting this environment variable like this probably isn't good idea when supporting multi-arch.

Same as above. This may not play well with multi-arch.

  • (nit) the hashbang doesn't need to go through env, that's just a limitation of FreeBSD that's irrelevant here (because 1. if FreeBSD grows MPTCP support, it won't use Linux-specific internal management interfaces thus this daemon, 2. it was fixed by making /lib/init/init-d-script a binary stub)
  • description: "Debian" is merely the first distro to support, any other that uses init scripts (Slack, Alpine, ...) can use the script as-is
  • description: "init script" is redundant here
  • messing with LD_LIBRARY_PATH is indeed unneeded and harmful
