It might not be hard for systemtap to parse dtrace's smaller scripting language, but there's more to it than that. A variety of dtrace kernel and userspace features have no equivalent yet, so many real dtrace scripts would not work. Plus, may dtrace scripts use type names/structs/fields that do not correspond to those in linux, so one would need to change those scripts or create a solaris emulation layer someplace.

And AFAIK they have not made a Solaris emulation layer, so Solaris-specific dtrace's script won't work here either.. A compatibility layer with dtrace portable scripts would be nice, but compatibility with OS-specific dtrace scripts doesn't matter much IMHO.
