Yes, the implementation of fileExists: was changed, so it no longer iterates over entire directory contents, but tries to open the file. Sadly, the Unix vm contains a bug which means relative links will not be resolved correctly. A fix from Cog has been submitted, but no release has been made which obtains it yet.

To run the test-suite for Magma 1.1r2 in Pharo:
- Proceed past two warnings about "FlapTab" when loading Magma. - Revert FileDirectory>>#fileExists: to the prior version. - Remove #testClassSchemaUpgrades. - Load OSProcess.
The second and third steps, above, I believe may be regressions in Pharo 1.1.
In Pharo 1.1:
FileDirectory default fileExists: '/bin/sh' "---> false"
but the file does, indeed, exist as a soft-link. Squeak answers true and, I'll bet, so does Pharo 1.0, so I'm not sure if there is a problem here or not.
#testClassSchemaUpgrades tests Magma's ability to keep up with class-schema changes in the image. Usually class-schemas change only in development, not production systems so maybe it's not a big deal. But still, it can be very convenient develop new class schemas while connected to a persistent Magma store. Magma makes use of the SystemChangeNotifier to do this. I don't know if Pharo cleaned something with SystemChangeNotifier or a regression happened, but I don't have time to debug it right now. Certainly, if there is a problem with Magma I will fix it, but I'm not convinced of that yet.
