Very likely. Try this: $ touch xyz $ attr -s foo -V bar xyz Attribute "foo" set to a 3 byte value for xyz: bar $ attr -l xyz Attribute "foo" has a 3 byte value for xyz $ attr -g foo xyz Attribute "foo" had a 3 byte value for xyz: bar And now for a small surprise: $ getfattr -d xyz # file: xyz user.foo="bar" $ setfattr -n foo -v baz xyz setfattr: xyz: Operation not supported $ setfattr -n user.foo -v baz xyz $ getfattr -d xyz # file: xyz user.foo="baz" $ attr -g foo xyz Attribute "foo" had a 3 byte value for xyz: baz See `man 5 attr'. All NTFS/Samba EAs are treated as extended *user* attributes. namespace. On Cygwin only user EAs are supported and mapped to NTFS/Samba EAs without the "user." prefix.
