I'm okay to be assigned to that, but I don't know if i have rights to modify or propose modifications to R2947.

@be1 That repo doesn't have a maintainers.md file so it's more or less fair game for anyone to modify. You just need to make sure that your updated package is well-tested with whatever depends on that package (which you can find out with eopkg info spice-gtk). Since you're just making a permission change on one of the bundled files and not something extensive that testing does not need to be exhaustive.

Thanks.
I tried the following command in install block:

setcap CAP_FOWNER=+ep $installdir/usr/lib64/spice-gtk/spice-client-glib-usb-acl-helper

but, despite there is no error reported at build time, the resulted extracted binary package doesn't contain the capability attribute.
Maybe the attribute is not kept in the archive file format ?

However, using

chmod 4755 $installdir/usr/lib64/spice-gtk/spice-client-glib-usb-acl-helper

is okay, but this is not optimal.

I don't know how to set a command to be executed at package install time. Thanks for your comments.
