 Has anyone implemented EPICS symbolic device support under the Linux OS

What do you need it to do?
If you just want something very similar to the vxWorks support you might
be able to hack something derived from the vxWorks code that uses the
linux dlopen(NULL, ...) and dlsym() routines.
I did spend some time last year trying to update the vxWorks code while
thinking about updating it to be used for any OS (requiring all
variables to be registered in the DBD file using variable() statements)
but I got side-tracked and gave up.
