SSH changes vs future firmware update

Question

Hullo, I have made some changes to WD My Cloud via SHH: I disabled ipv6;I stopped two services through crontab (S85wdmcserverd and S86wdphotodbmergerd)etc, according to http://blog.cloud-client.info/?p=1365 In case of future firmware update and I perform the installation will the changes done be overwritten?Would be advisable to accept the update in the future? Thank you in advance.

Indeed, an answer from a user that has experienced the aggravation of firmware updating and vowed never again will he update; unless he has two clouds (one to update and the other to keep as backup). yes... once you update your firmware, all changes will be lost and if you had store script files in the /usr/local/sbin directory, they will be gone too... In a sense it is a good thing because if you had done a lot a changes, this reverts your device back to original factory state. Now I have heard rumors that if you by pass too many firmware updates and decided to upgrade from, lets say 3.04 (which happens to coincide with my current version) to the latest firmware 4.xxx which is probably 6 update versions ago, your device will be bricked. They say, the customers that runs and replies in this forum, that you will need to upgrade your firmware one by one until you reach the latest version. The other rumor is that many have updated their firmware to the latest version to find that nothing works, speed is slower, usb connections don't connect and of course drop outs are more frequent. Then there are those who says "I've upgraded and everything is fine", but that particular user probably has 5MB of data on his drive. Now here is what I suggest. 1. Always have another copy of your data which has nothing to do with firmware updates. Never ever copy your data to the Cloud device and erase the original unless you have another copy somewhere else. If you don't have another device and don't wish to buy another device, either leave the original on your original drive and use the Cloud as your backup, or subscribe to one of the free or paid online storage to keep a backup copy, but don't rely on the online storage as your only copy either, since places like Megaupload may disappear overnight and your only copy may be in the hands of the FBI.2. if you upgrade your firmware, it is better to have another Cloud for a 3rd backup. That way if something fails (and it would feel like it expecially when it goes white light on you), you have another device to use while the other one is being RMAed.3. If you have stopped the scans from occuring, the first thing that happens after an update is a flurry of activity from your Cloud trying to catch up on its scans and you might get locked out. So be prepared to SSH into it as soon as it lets you which is way way after the white light stays on for several hours (speaking from experience). 4. Once you SSH in, be prepare to repeat the fixes that you applied to your last version. For four years (or more), I haven't seen a switch to turn off the media scans although in version 3.04, they actually turned off the scans automatically dues to processor overload and it had a message on the UI telling me that the scans has been stopped and in order to restart the scans you must reboot (I didn't reboot for 6 months). You can skip firmware upgrades as I have without too much problems. Although they have fixed a couple of potential security threats, none of them should potentially affect you since you are behind a router. Although eventually I expect that I will have to upgrade my firmware simply for the reason that the matching iphone app will require the latest version. Perhaps on that day, I will sell my Cloud and move on to a more robust NAS. Good luck..  edit: the/bin/sh /etc/rc2.d/S86wdphotodbmergerd stop /bin/sh /etc/rc2.d/S85wdmcserverd stop  are not permanent changes. If you reboot the Cloud, those two process will restart. The update-rc.d commands will disable the processes until you upgrade the firmware.
