Every local mount in /etc/fstab will be added as a dependency to
local-fs.target, and every remote mount to remote-fs.target. If you pull
those two in by default.target then everything from /etc/fstab will be
mounted during boot.

Not sure I understand the question.

But like everything on Unix you are supposed to return 0 when you
succeed. Note that systemd by default considers services with no running
process failed. You need to set ValidNoProcess=yes in the .service files
to tell it that having a service around with no process is OK. This
especially necessary if another service depends on this service and
shall continue to run.

For every service referenced systemd will first look for native service
configuration files, and if they don't exist look for SysV init
scripts. You should not need to make any adjustments for that...
