As I said, it's just what I hear =97 perhaps it's the usual retrograde whining. I should probably just try udisks-glue, the only issue I see is that it depends on UDisks 1. > You can stall the whole hotplug path, causing issues and overruns.

Perhaps I wasn't expressing myself clearly =97 the point was to show that mdev is not needed. I used mdev in initramfs previously, but now rely on devtmpfs and the one-liner /sbin/hotplug for loading modules. Incidentally, turning off mdev resulted in Busybox executable size change of precisely 0, which I guess shows how much mdev actually does. > I really want to get rid of that entry and option from the kernel entirel= y Please don't =97 it's useful in Busybox-based initramfs. Dracut-like inclusion of udev and its dependencies DAG is usually unnecessary and an overkill. --=20 Maxim Kammerer Libert=E9 Linux (discussion / support: http://dee.su/liberte-contribute)
