POSIX sh syntax is supported everywhere. If you ever discover a distro that has a non-POSIX /bin/sh, and report it as a bug, they will treat it seriously and fix it. $ORIGIN is a non-standard feature of GNU ld. Granted, given that it's documented, it will probably work everywhere forever anyway, but it's more likely that a weird distro will switch to a different linker with slightly different rules, than switch to a standards-violating shell.

The explanation there shows that this is an explicitly supported feature. I just found out about $ORIGIN recently too, and was just as excited as you are.

If $ORIGIN isn't even mentioned in the manual, can you rely on it? (I don't know, maybe it's in the ELF standard or something). /bin/sh is required to be a posix compliant shell on linux nowadays though.

Symlinking would work. Ideally replace libraries in /lib/lib1 to use different libraries. Symlinking would work.

Binary compatibility across distributions has always been a nightmare for commercial developers. I wrote about this in a series of articles on gamedev.net, and shared some great tips given me by Gerry Jo Jellestad for achieving binary compatibility. This could be a good alternative to using a startup script to set the LD_LIBRARY_PATH and run the game. I'll have to experiment with this a bit, and perhaps update my articles.
