Hi, I'm developing an IOKit kext (my kext's class is derived directly from the IOService) that opens some files (vnode_open(...)) on the root filesystem. These files must be closed (vnode_close(...)) before the system tries to unmount the root volume (if these files are not closed an unmount will fail). Is there any way to receive notification about an impending shutdown or restart before an unmount of the root volume? This email sent to site_archiver@lists.apple.com
