[oi-dev] ntfs-3g and fuse

[ken mays]

Jean-Pierre,

What is your current analysis (if any) with ntfs-3g_ntfsprogs-2012.1.15 ?? Just fuse kernel module issue?

Currently it is build from spec-files-extra (http://pkgbuild.sourceforge.net/spec-files-extra/) which is using the last OpenSolaris.org FUSE tarball (it contains head of the FUSE repo) + your patches, then it is pulled by SFE OI. What I did it was that I took the tarballs (opensolaris.org and your) and created diff and pushed the diff to spec-files-extra.

Sure, but I am not the maintainer of fuse (and I do
not want to), nor the packager for OpenIndiana.
My job is only to answer problem reports on ntfs-3g.

I agree.

That is a nice proposal. My patches are at your disposal.

Regards

Jean-Pierre
