Hej all,
Because of the discution about the python dependencies for systemd-analyze
I made a rewrite in C.
The patch is available from my github repo[1] so please test it.
(especially efi systems with gummyboot since I am still stuck with BIOS)
What is new about this c implementation?
- written in C.
- no deps on graphical libraries.
- fixes a bug in 'blame' where systemd-analyze would skip oneshot services.
- generates cleaner svg files.
- can serve as a basis for further bootchart/analyze intgration.
- faster[2]: (numbers from my netbook)

Changes between this version and the one Auke published:
- code deduplication.
- removal of unnescecary copy pasted code.
- fixed the 'blame' bug mentioned above.

[2] even though it is not performance critical it feels a lot smoother now.
