This doesn't even actually do anything right now. This is C, you can't
do this:
https://github.com/ServiceManager/ServiceManager/blob/master/app/resta
rtd/unit.c#L21.

This project is like 200 lines, why can't they write proper memory
allocation routines? If you think a modular design is all that's
needed to replace systemd then be prepared for random crashes and
memory corruption.

Good luck, maintainer!

What's wrong with that line? No error handling?

Yeah, the "allocated" memory is immediately modified without checking
the return status. This project is supposed to be an *init* system.
Like, the program that starts when your computer boots. What happens
when the kernel kills this program because it's trying to access
unallocated memory? Yeah. Not fun.

What's fun about its name is that XVI is a hidden ХУЙ, which is a mean
word. System Dick, I like it!

In such a situation that the routine you see there fails, process
tracking stops working. That being the core of restartd, your system
becomes somewhat useless.

Personally I do not see such great value in checking the return value
of malloc() in a world where memory overcommit means even a 'valid'
pointer might point not to memory but straight to SIGSEGV. Still, this
seems to be a popular request, and I will begin checking malloc()
return and backing out of operations where this fails.

Do be aware, though, that 'self-healing' is one of the Four Motives of
S16. If restartd crashes it will be immediately restarted by init and
will be able to recover service state from the repository.
