Attached patch does that.
No. As Tom pointed out, /usr is package manager territory and exactly the same on all machines (with the same set of package installed at least). It's supposed to be sharable between hosts. Doing recursive checksumming of /usr (modulo /usr/local) should yield the same results on all installations with the same package set. hwdb.bin is data that is generated dynamically on the host, and is possibly different on the various installation. It hence has no place in /usr. Of course /etc isn't particularly beautiful for this either, since it doesn't match *conceptually* what else is stored on that partition, but at least it has the right *availability*, *shareability* and *access* guarantees. /var doesn't work for this, as /var might be mounted too late. Introducing a new directory /cache or so would certainly work, but given that this problem exists only for the very minimal set of early-boot services this sounds like too big a change. And yeah, there are some other things in /usr that are currently generated on the host, and that should better be moved to /etc. Lennart -- Lennart Poettering - Red Hat, Inc. _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
