Antoine, All,

On 2020-10-06 17:37 +0200, Antoine Tenart spake thusly:
> This patch sets the --with-xattr option when generating an image with
> mkfs.jffs2 if BR2_PACKAGE_LIBSELINUX is selected, so that SELinux
> security contexts will be kept and available in jffs2 images.

Does that means that, if people are using extended attributes in their
device tables [0], then their jffs2 filesystem will not carry those
xattrs?

Basically, I fiond it dubious that a filesystem option depens on a
package being enabled or not.
