The problem I see with alternatives is: what happens when I have init X
set as the current alternative and I boot into init Y with a kernel command line
or with a Grub-init-Y line?
Will I end up with init Y but with all links pointing to init X commands?

Possible gains I see are:
* less complexity in maint scripts
* deal with multiple inits installed and
booting in a non default init at one time
I can summarize that checking every time for the current init
may look worthless but it's more robust then one-time check.
In the middle there is the "more-then-one-check" solution, setting the
alternatives at install, at boot and i don't know where else, but here
