Since your issue only affects signing of other keys - which normally is not a daily scenario - what about using a GNU/Linux live system/CD/USB for that purpose? That way you can use a normal GNU/Linux supported filesystem and don't have to worry whether to trust your normal OS or which filesystem is compatible with all OSses you intend to use. ~flapflap _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
