I really would like to see the hotplay replay since September :) https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id3841#c6 Basic problem for Fedora Core: 1. initramfs: - modules have to be loaded, devices have to be created with udev - the linuxrc does not know, when the devices are created, so it just calls udevstart several times after module loading (workaround) - hotplug events are not processed completly, because "/" is not mounted yet 2. SysVinit: - important hotplug events are missing, after "/" is mounted rw (e.g. loading of scsi modules after the scsi-adapter module was loaded in initramfs) ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
