Yes, it really is.

OpenELEC is built from the ground up to explicitly include only the bare minimum of what is required. Kodi Live starts from a full Linux distribution and pars down from there, meaning your install contains large amounts of content you don't actually need. Also, OpenELEC is an appliance - meaning trivial system wide updates including Kodi. Live requires Linux knowledge and time to maintain. OpenELEC maintains itself automatically.

Since OpenELEC 4.0 (gotham) the only build available for x86 machines is the Generic build.

One of the well-known SSH tools is from http://www.putty.org, which is available in many flavors including Windows and Ubuntu Linux. Linux and OSX can use ssh by simply opening a terminal window and using the ssh command.

Currently the login into OpenELEC has fixed settings.

Login: root
Password: openelec

Note that these values are case-sensitive.

Directory listing
ls -la (-la will include all hidden folders and/or files)

Make Directory
mkdir <foldername>

Change Directory
cd <foldername>

Copy File(s)
cp <source_foldername>/<sourcefile.ext> <target_foldername>/targetfile.ext (single file)
cp <source_foldername>/* <target_foldername>/ (several files)

At the moment it's not possible to change the root password as it's held in a read-only filesystem. However, for the really security conscious advanced user, you can change the password if you build OpenELEC from source. Also you can consider logging in with ssh keys and disabling password logins.

In the short term there will not be a roadmap. In these early days plans are changing as the OpenELEC team evolves. This may change in the future.

OpenELEC and Kodi are two different open source projects. Whilst there is some staff overlap and a good relationship between the projects they are discrete.

Yes, but please contact us to discuss first since it will increase our support workload.

In any way you see fit. Open source projects run on contributed code, donations, support in the forums and documentation. We welcome all assistance.

There is no swap partition by default in OE. It really isn't needed anyway as most systems have over 1GB of ram which is more then enough.

We strive to support as many hardware devices as possible. We do have a list of supported hardware, although it's not complete so if your hardware isn't listed that doesn't mean it won't work. Since OpenELEC can be installed to a USB key, you can try it on your system without affecting the OS you're already running to see if your hardware is compatible or not. Either way, create a post in our Supported Hardware forum so we know. If it doesn't work, we'll do our best to add it in our next build. List of supported hardware

Definitely, however you need to be prepared to assist us. Post in the forum and wait for specific questions. Respond promptly, developer time is precious.

Yes there is! Raspberry_Pi_FAQ

Yes, it is possible. Dual boot systems with OpenELEC and another OS but we do not support it. Even triple boot systems are possible (Windows / Linux / OpenELEC). OpenELEC is meant to own the whole hardware and if you want to dual boot you accept the risk in doing so. Help is available in the forums.

Sure. If it is useful to the majority of OpenELEC users and it and all it's dependencies can be added without compromising the project's goals then it would be viable for addition as a core feature. If it is large or of less overall interest it should be requested as an Kodi add-on.

Via the OpenELEC forum or IRC/chat channels. Remember support is free and fuelled by volunteers. Be courteous, patient and above all prepared to do your part. Remember to search the site guides and forum thoroughly BEFORE requesting help.

Simply accessing the Logfiles Samba share and a ZIP file full of support logs will be created for you. Upload this file to your favourite cloud drive and provide the link for others to help you out. :-) Guide to Accessing Samba Shares
