>Description:
This adds a file flag which can be used as a hint to applications
(especially GUIs) that a particular file or directory should not be
displayed to the user by default. For Windows file systems, this would
be mapped to their native "hidden" attribute. For Macintosh file
systems, this would be mapped to the "invisible" bit of the Finder Info.
The patch includes a libc change to strtofflags(3) and fflagstostr(3)
mapping the bit to the name "hidden" so it can be accessed via ls(1)
and chflags(1).
The patch also maps the Windows "read-only" attribute bit to the
UF_IMMUTABLE file flag (for both msdosfs and ntfs).
This change originated in Mac OS X (in a version not yet released).
The patch is offered to help keep the file flags in FreeBSD and
Mac OS X in sync.
>How-To-Repeat:
In the Windows GUI, select a file on a FAT or NTFS volume.
Right-click on the file and select "Properties" from the menu.
Check the box titled "Hidden".
Take that disk to a FreeBSD machine and do "ls -lo" on it.
With this patch, "hidden" will be displayed in the flags column.
