Linux – Different Shell for Root and Non-Root User

According to the FAQ:

In FreeBSD's case, the reason is that csh is the only shell "guaranteed" to be on the base filesystem (stuff from ports usually winds up in /usr/local/bin, which defaults to a different filesystem). This is important because you don't ever want there to be a situation where root can't log in because it's using a shell on a different (unmounted) filesystem.

Even though these appliance type products are based on Linux it's generally a good idea not to try and customize them as though they're Linux boxes. They typically are missing most of the tools and are usually stripped down in various ways which can make this dangerous.

I've had experience with both Netgear's ReadyNAS box as well as the Thecus boxes and this has always been the case with both these types of products. You might want to consider doing a factory restore to get this back normal instead of hacking it your self.

You'll have to reconfigure the box but this is usually just setting the IP back up and potentially some user account creation.

I direct you to the actual pages from Synology that cover how to accomplish this:
