Hi, After replacing busybox sed with 'sed' binary, the umount.aufs is working fine. However I have further problems while system shutdown. First of all after I modprobe aufs and create aufs mounts, I'm seeing four processes in ps output as 'aufsd' !! ps -ef | grep aufs 481 root [aufsd] 482 root [aufsd] 483 root [aufsd] 484 root [aufsd] Does aufs start/use any daemons ? Now, during shutdown,since I'm creating aufs unions on /bin,/sbin,/lib and /usr I cannot straightaway umount them ( I get umount: /bin: device is busy ), hence I do lazy unmount ( umount -l ). After I do umount -l /bin /sbin /sbin /lib ( or an equivalent umount -a -l -t aufs ), I still see those four processes running ! If I unmount from the command line and then do a modprobe -r aufs, then only the process go away. If I do the same thing using rc.shutdown process, unmount happens fine, but modprobe -r says: Resource temporary unavailable and the module doesn't get removed. What happens due to which is, when the shutdown script ( rc.shutdown ) tried to remount root filesystem read-only ( mount -o remount,ro / ) , the kernel says: umount: / : device busy ! So, the ext3 root filesystem is not getting shutdown cleanly ! Kindly provide some pointers here....
