I don’t see any reason why should sys-block/open-iscsi require udev. This dependency was introduced in 2.0.872-r3 with reference to #556632. If I understand it correctly, it’s just about copying some rule files and scripts. This can be optional (USE udev?). Why it bothers me? I don’t use either udev or eudev, simply because I don’t need such a complex and bloated solution on a server; busybox’s mdev is perfectly fine for me. However, mdev is not in virtual/udev, so it doesn’t satisfy this dependency. Reproducible: Always
If udev is a runtime-optional then it shouldn't even be in RDEPEND, but just be printed via elog in pkg_postinst(). Also, I think those files could be installed unconditionally, so there's no reason for an udev flag at all IMO.
Let me rephrase what hasufell said. Is there ever any reason to disable udev rules here? If there is, the patch looks acceptable to me. If there's not, we shouldn't have USE=udev and it'd be fine just to remove udev dependency... well, since it's more of a reverse dependency.
the udev rules are only used to probe devices automatically, so there's no need to depend on it http://gitweb.gentoo.org/repo/gentoo.git/commit/?id=f2c1a8a62739b9cbbcb05c8af541383cdb1caa4f
