I think the #1 priority from here on needs to be to get better interoperability for NTFS and ext3 going in the main Indiana OpenSolaris distro (2008.11). ReiserFS support and XFS read/write support would be nice as well. So far, I think the leaders for doing this sort of thing have been the guys from Belenix. Belenix is a free, opensource, OpenSolaris based-distro that uses a KDE desktop environment and seems to be a little bit ahead of the main Sun-sponsored Indiana (2008.05) distro in terms of implementing a lot of file-system related features such as porting GNU parted and getting NTFS support.
What you could do is you could try to get ReiserFS support added to the list of Belenix projects here: http://www.belenix.org/projects or you could hang out at the Belenix chatroom here: http://www.belenix.org/belenixchat and talk to the developers and find out what they think about ReiserFS support. The only caveat about the Belenix chatroom is that the developers live in India, so I'm not sure what time they would be on there. I believe there is another distro called Nexenta (basically Debian/Ubuntu with a Solaris kernel) that might already have ReiserFS support, since ReiserFS support exists in Debian/Ubuntu and Nexenta intends to ultimately have all of the GNU / Debian / Ubuntu feature set running on top of ZFS and the Solaris kernel. You could go here: http://www.nexenta.org/os and find out if Nexenta supports ReiserFS (I think they already do, but I'm not sure). -- This message posted from opensolaris.org
