Are these the only ones symlinked?  I bet this:

> 2953  open("/usr/lib/YaST2/plugin/libpy2wfm.so.2", O_RDONLY) = 7

is a symlink to /mounts/instsys, and this:

is not.

I don't know what to suggest.  The real location of the file, on an
installed system, is probably relative to where the real debug info
will be found.

You can work around this with a couple of creative symlinks.  For
instance:

> 2953  open("/mounts/instsys/usr/lib/YaST2/plugin/libpy2wfm.so.2.0.0.debug", O_RDONLY) = -1 ENOENT (No such file or directory)
> 2953  open("/mounts/instsys/usr/lib/YaST2/plugin/.debug/libpy2wfm.so.2.0.0.debug", O_RDONLY) = -1 ENOENT (No such file or directory)
> 2953  open("/mounts/instsys/usr/lib/debug//mounts/instsys/usr/lib/YaST2/plugin/libpy2wfm.so.2.0.0.debug", O_RDONLY) = -1 ENOENT (No such file or directory)

The third path is wrong for you, but you can make the second path
right.  Symlink /mounts/instsys/usr/lib/YaST2/plugin/.debug to
/mounts/instsys/usr/lib/debug/usr/lib/YaST2/plugin.
