Usually I don't post too often in threads that can be interpreted as 'contentious', but given the title, this one fits right in.
There is an even bigger insecurity in Raspbian: systemd. Some claim it's the best thing since Linus Torvalds wrote the kernel, Linus himself isn't too sure about systemd however. Read on for your own judgement:
(note: no affiliation, but IMO they have a number of valid points!)
Raspbian is based on Debian, as we all know, and the Debian folks decided remarkably quick to ditch the "ancient" (but functional!) SysVinit system for systemd (that fails consistently on my non-RPi hardware*), making sure sysvinit was really only available for those dev's that knew how to get rid of the systemd dependency chain to get a decent, working system. For me, it meant looking for a suitable Debian replacement. Gentoo-based Funtoo holds the best cards now, but that's personal choice of course
I haven't gotten as far as to compile it for the RPI, that'll only happen after obtaining some RPI2 replacements of the current crop of Model B's I have. That'll be a while, other priorities take precedence.
(*if you wanna know: it doesn't allow me to shut down properly, I have to do a hard-shutdown with the power button. After replacing systemd with sysvinit, everything works again
No, I don't want systemd workarounds, I want systemd fixed and thus adhering to the proven Linux/Unix adagio "one tool, one job done perfectly". Yes, I dislike systemd, as you guessed correctly
