Sorry, but if ads were simply generated on the webserver itself (in case of slashdot), with images that also come from slashdot itself, or - in case of something like wordfeud - the ads are simply proxied by the app's home base (apps also phone home for stuff, right?), then the ad-traffic becomes indistinguishable from other, necessary traffic and ad-blockers would be out of work, right?

Yet this doesn't happen. So apparently, it is still too easy to serve apps.

Comment Re:Only incidentally similar to su (Score 1) 747

It's a privilege escalation inside a very complex environment. Su is a simple shell interface to a system call.

I'll tell you what - as long as I can turn the option of escalation privilege to arbitrary processes off inside systemd, in a safe and predictable manner, and the option to turn it off is heavily documented, I'm happy.

Su is not a broken concept; it's a long well-established fundamental of BSD Unix/Linux.

You're pretty much making an argument to tradition here. The correct thing to do would be to counter his claims:

what "su" is supposed to do is very unclear. On one hand it's supposed to open a new session and change a number of execution context parameters (`uid`, `gid`, `env`, ...), and on the other it's supposed to inherit a lot concepts from the originating session (`tty`, `cgroup`, `audit`, ...). Since this is so weakly defined it's a really weird mix&match of old and new paramters.

I would like more detail from him on why and how it's broken, and how his replacement is truly different from "su -" but since it doesn't appear to be mutually exclusive with the use of "su" or "su -", other than typical reactionary hate I don't see what the problem is.

99% of the execution context changes and things that stay the same that su cause, happen in any subshell. Does Poettering dislike subshells as well? Does he dislike shell scripts?
