The sysfs layout changed since kernel 2.6.18. I'm guessing the use of CONFIG_SYSFS_DEPRECATED and/or CONFIG_SYSFS_DEPRECATED_V2 will interfere with my script in current kernels. I'll poke around in one of my VMs when I get a chance. > Now I need to find udevadm I guess. It must have been introduced since the udev version that comes with RHEL/CentOS 5, which is udev-095-14.21.el5_5.1. rpmfind.net suggests it's only been in since version 118 or so. Never mind :-) Heh. Anyone know the equivalent command in earlier versions of udev? > > Cheers, > > John. > Regards, Phil -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
