[Trisquel-users] Re : Could systemd be an inconvenient on portability?

[lcerf]

I'm not against using features that aren't available on other *nix systems in  
general, just against unportable system components that can become  
dependencies of programs.

Well, as long as you use a feature that is absent from another kernel, it  
will not work on that other kernel. A fallback can be implemented when the  
feature is a detail. In the case of systemd's pid 1, the cgroups are central  
to the design (so that daemons cannot escape management, not even by  
double-forking). The real solution for other operating systems that want  
systemd is to have their kernel catch up with Linux. As far as I understood,  
GNU Hurd's developer are actually considering the implementation of a  
cgroups-like feature so that systemd could work on top of it.
