At one point, I had read that initscripts is slow compared to systemd 
because it reads all the damn text files and has to parse it first, while 
with systemd, it is all binary. Now that I look back, I realize, the 
author must have been talking about initscripts and not the configuration 
files. My bad there, I agree. 

I was talking about text configuration file. I had this mistaken idea all 
the time that since now, we have systemd which is binary implementation, 
the text files are also converted to binary to reduce the time in 
fetching and parsing them and hence, reduce the boot times even more. I 
guess, the readahead implementation was what I was confused with, which 
is just prefetching, not binary.

I know those are bash scripts, but my above point explains it I guess. I 
was talkign about reading configuration "text files" vs binary files. 

I still believe that there should be a script/program which can output 
all the configurations from different file onto the terminal describing the 
currently configured boot process.
