From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.0.2 (X11; Linux i686; U;) Gecko/20011226 Description of problem: /etc/rc.d/rc.sysinit trys to unmount /initrd. However, if the initrd uses devfs, then this unmount fails because devfs is mounted at /initrd/dev. Since /initrd/dev can not be mounted until after chroot executes init in the initrd linuxrc script (following a call to pivot_root), /initrd/dev/must be unmounted by rc.sysinit. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Make an initrd that supports devfs and have its linuxrc mount devfs at /dev. 2. Linuxrc executes pivot_root and "chroot ... init". 3. Rc.sysinit tries to unmount /initrd but fails because /initrd/dev is a mounted devfs. Actual Results: Unmount of /initrd by rc.sysinit fails. Unmounting all filesystems at system shutdown also fails. Expected Results: /initrd and /initrd/dev should have been unmounted as they are no longer needed.
