It seems my device doesn't have init.d support, but I have a bunch of init.* files. Can I use the same approach somehow?

Question

-rwxr-x---    1 root     root          3265 Jan  1  1970 init.class_main.sh
-rwxr-x---    1 root     root          1730 Jan  1  1970 init.mdm.sh
-rwxr-x---    1 root     root          3347 Jan  1  1970 init.mmi.boot.sh
-rwxr-x---    1 root     root           325 Jan  1  1970 init.mmi.dtv.sh
-rwxr-x---    1 root     root           562 Jan  1  1970 init.mmi.early_boot.sh
-rwxr-x---    1 root     root          6341 Jan  1  1970 init.mmi.touch.sh
-rwxr-x---    1 root     root          8592 Jan  1  1970 init.mmi.usb.sh
-rwxr-x---    1 root     root          7054 Jan  1  1970 init.qcom.class_core.sh
-rwxr-x---    1 root     root          6920 Jan  1  1970 init.qcom.early_boot.sh
-rwxr-x---    1 root     root          6987 Jan  1  1970 init.qcom.sh
-rwxr-x---    1 root     root          2962 Jan  1  1970 init.qcom.syspart_fixup.sh
-rwxr-x---    1 root     root          2844 Jan  1  1970 init.rc
-rwxr-x---    1 root     root          1327 Jan  1  1970 init.recovery.usb.rc
-rwxr-x---    1 root     root           683 Jan  1  1970 init.surnia.sh

These are all the files that begin with init.* in my /partition. In /system/etc I have some as well:

-rw-r--r--    1 root     root          2767 Mar 26  2015 init.ath3k.bt.sh
-rw-r--r--    1 root     root          1773 Mar 26  2015 init.crda.sh
-rw-r--r--    1 root     root          4987 Mar 26  2015 init.qcom.audio.sh
-rw-r--r--    1 root     root          9938 Mar 26  2015 init.qcom.bt.sh
-rw-r--r--    1 root     root          3651 Mar 26  2015 init.qcom.coex.sh
-rw-r--r--    1 root     root          3791 Mar 26  2015 init.qcom.debug.sh
-rw-r--r--    1 root     root          1725 Mar 26  2015 init.qcom.efs.sync.sh
-rw-r--r--    1 root     root          3083 Mar 26  2015 init.qcom.fm.sh
-rw-r--r--    1 root     root          4023 Mar 26  2015 init.qcom.modem_links.sh
-rw-r--r--    1 root     root         54877 Mar 26  2015 init.qcom.post_boot.sh
-rw-r--r--    1 root     root          2767 Mar 26  2015 init.qcom.sdio.sh
-rw-r--r--    1 root     root         19105 Mar 26  2015 init.qcom.wifi.sh

Are these similar to the init.d feature? How can I check if these init.* are run at boot? If so, how can I use this structure to add a custom script to run at boot?

There's no "easy way" in my scenario. My search found so far plenty of options:

The simpler way is to use an APK to emulate init.d: https://github.com/Androguide/Universal-init.d or https://github.com/Grarak/KernelAdiutor
