We have FC4 in the linux base port. Fedora Legacy is abandoning it, so =20 no security updates anymore. FC5 and later require a 2.6 kernel, they =20 don't run with a 2.4 kernel. So we need the 2.6 emulation rather =20 sooner than later. A reason to not enable the 2.6 emulation currently is: we have =20 showstopper bugs. Acroread is not working. We have a patch for this, =20 but we are discussing some details (security implications and locking =20 stuff). So far I didn't had time to test the functional change of this =20 patch and don't know if it fixes all issues with acroread or not (I =20 know about several ways if cashing acroread with 2.6, other people =20 know only one way (immediate crash at startup), because I'm the only =20 one with an acroread configuration which allows to start acroread =20 (without specifying a PDF) withhin 2.6 without the above mentioned =20 fix). And there may be some other bugs we didn't stumbled upon yet. =20 Because of the showstopper bug and the fact that the amd64 part is =20 only available in p4 ATM, we didn't had widespread testing of the 2.6 =20 emulation. So currently the strong reason to not enable it by default is: major =20 bugs, lack of amd64 support and no widespread testing. When we fixed the showstopper bug with acroread and don't identify =20 another major bug, I will ask for testing 2.6 on -current to identify =20 the easy to find bugs. After a week or two I will change the default =20 emulation to 2.6 in -current, except we have some showstopper =20 problems. At this point I also hope to have the code for amd64 in the =20 tree. If 2.6 will be enabled by default in 7.0 has to be determined based =20 upon the feedback then.
