Do you know the reason why FileVault prevents this kind of execution?
I thought it was a simple encrypted disk image containing the user

FileVault is no different from any other disk image in this respect: disk images are always mounted nosuid/nosgid/nodev. If they weren't, you could download a disk image with a suid binary, mount it, and gain admin access.

The fact that this applies to FileVault is an unfortunate result of the way that it's implemented. _______________________________________________
