Package: ntfs-3g
Version: 1:2009.4.4-1ubuntu4
Severity: normal
Tags: patch
Here is a patch from LinuxDeepin, which can provide extended attributes
supported in ntfs-3g, the author is Jiahua Huang <jhuangjiahua (AT)
gmail (DOT) com> and licensed as the same as ntfs-3g package in Debian.
I don't know if this patch can be accepted to provide such a function in
Debian.
LinuxDeepin has tried to make it possible to install Linux on an ntfs
partition with ntfs-3g, I think it is a good feature at least for the
newer comers of Linux.
Regards,
Aron Xu
