Converting the legacy sysv init script for livesys and livesys-late service

[Jóhann B. Guðmundsson]

Greetings

I'm currently looking at converting the legacy sysv init script that get 
created by the ks files to a native systemd unit files for the spins and 
at the same time looking into tuning the boot up process for live runs.

Now instead of cluttering the ks file with creation of the unit and the 
tuning I have moved this into a seperated package which each spin would 
have to install at install time( if accepted as an solution since this 
is in a package it will be a change in your current workflow ) and 
ofcourse -$package that other ks. would pull in.

I have created a Proof Of Concept package for LXDE contains the 
following...

Tweaking parts in the spec file to disable service that are not needed 
to run on the live image.
( note this is just an example for what can be achieved rather than what 
should be done system analyze plot shows lxde booting up in 55 seconds 
and ofcourse you can just delete that tweaking section from the spec 
file along with removing the relevant "restore-service-state" section in 
it if you dont want to tweak the bootup at all  )
2 unit files livesys.service and livesys-late.service that both disable 
itself after being run  ( which the legacy sysv did not do )
2 scripts that are simply the legacy syv init scripts standalone as 
created for lxde in the ks.file
1 script that restores what got disable when the package got installed 
which ( in theory ) should a user install the live image and or run a 
live image with persistent storage those services will be available to 
him after install ( and by available I mean running as they would have 
been on the livecd before tweakin ) or encase of live usb with 
persistent storage on the next reboot.

I was planning on having a working POC before posting this but 
unfortunately the LXDE owner has been unresponsive both on irc and 
private mail I sent him but to not keep this discussion from happening 
since moving this stuff into a package is a change in spins workflow I 
decide to post this here to get the discussion going.

If someone has the time to actually test this with me and see if this is 
achievable et all then mention that on this thread and or contact me 
privatly and I will convert your spins and create a (s)rpm which you 
would just install.

Thanks.
