.deb/.rpm: various fixes related to non-root

* Explicitly chown /var/lib/osmocom to osmocom:osmocom, instead of
  relying on systemd to do it when the service starts up. This does not
  work with the systemd versions in debian 10 and almalinux 8.
* deb: Use "useradd" instead of the interactive "adduser" perl script
  from Debian. This makes it consistent with how we do it in rpm, and
  avoids the dependency on "adduser".
* deb: Consistently use tabs through the file, instead of mixing tabs
  and spaces.
* deb: Remove support for the "dpkg-statoverride --list" logic. This
  seems to be a rather obscure feature to override permissions for
  certain files or directories, for which it does not seem to be a good
  idea to make the postinst script less maintainable. Something similar
  can be achieved by using your own Osmocom config file in a different
  path with different permissions.

osmo-msc - Osmocom MSC Implementation

This repository contains a C-language implementation of a GSM Mobile Switching Centre (MSC) for 2G (GSM) and 3G (UMTS). It is part of the Osmocom Open Source Mobile Communications project.

OsmoMSC exposes

  • A over IP towards BSCs (e.g. osmo-bsc: 3GPP AoIP or SCCPlite
  • IuCS over IP towards RNCs / HNBGW (e.g. osmo-hnbgw)
  • MGCP towards a co-located osmo-mgw for the RTP streams
  • GSUP (instead of 3GPP MAP) towards osmo-hlr
  • SMPP towards any external SMS sending/receiving applications
  • MNCC as external call-control interface towards e.g. osmo-sip-connectr
  • The Osmocom typical telnet VTY and CTRL interfaces.
  • The Osmocom typical statsd exporter.

OsmoMSC implements

  • mobility management
  • call control (either via built-in MNCC handler or external osmo-sip-connector)
  • voice group call (VGCS) and voice broadcast calls (VBS) as used in GSM-R
  • USSD (exposed via GSUP)
  • SMS (either via built-in SMSC or external via GSUP)

History

OsmoMSC originated from the OsmoNITB project, which started as a minimalistic all-in-one implementation of the GSM Network. In 2017, OsmoNITB had reached maturity and diversity (including M3UA SIGTRAN and 3G support in the form of IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one approach to fully independent separate programs as in typical GSM networks.

OsmoMSC was one of the parts split off from the old openbsc.git.
