I changed pivot_root+chroot to nash switch_root and the problem continues. The new /proc/mounts is: [EMAIL PROTECTED](~)# cat /proc/mounts rootfs / rootfs rw 0 0 /dev/root / ext3 ro,data=ordered 0 0 /proc /proc proc rw 0 0 none /mnt/router tmpfs rw 0 0 /dev/hdc /mnt/router/cdrom iso9660 ro 0 0 /dev/loop0 /mnt/router/etfw ext3 ro,data=ordered 0 0 /dev/loop1 /mnt/router/cdrom/tmpdir/1 cramfs ro 0 0 /dev/loop2 /mnt/router/cdrom/tmpdir/2 cramfs ro 0 0 /dev/loop3 /mnt/router/cdrom/tmpdir/3 cramfs ro 0 0 /dev/loop4 /mnt/router/cdrom/tmpdir/4 cramfs ro 0 0 /dev/loop5 /mnt/router/cdrom/tmpdir/5 cramfs ro 0 0 /dev/loop6 /mnt/router/cdrom/tmpdir/6 iso9660 ro 0 0 /dev/loop7 /mnt/router/cdrom/tmpdir/7 cramfs ro 0 0 /dev/loop8 /mnt/router/cdrom/tmpdir/8 cramfs ro 0 0 /dev/loop9 /mnt/router/cdrom/tmpdir/9 cramfs ro 0 0 /dev/loop10 /mnt/router/cdrom/tmpdir/10 cramfs ro 0 0 /dev/loop11 /mnt/router/cdrom/tmpdir/11 cramfs ro 0 0 /dev/loop12 /mnt/router/cdrom/tmpdir/12 cramfs ro 0 0 /dev/loop13 /mnt/router/cdrom/tmpdir/13 cramfs ro 0 0 /dev/loop14 /mnt/router/cdrom/tmpdir/14 cramfs ro 0 0 /dev/loop15 /mnt/router/cdrom/tmpdir/15 cramfs ro 0 0 none / aufs rw,xino=/mnt/router/etfw_changes/.aufs.xino,br:/mnt/router/etfw_changes=rw:/mnt/router/cdrom/confs=ro:/mnt/router/cdrom/tmpdir/15=ro:/mnt/router/cdrom/tmpdir/14=ro:/mnt/router/cdrom/tmpdir/13=ro:/mnt/router/cdrom/tmpdir/12=ro:/mnt/router/cdrom/tmpdir/11=ro:/mnt/router/cdrom/tmpdir/10=ro:/mnt/router/cdrom/tmpdir/9=ro:/mnt/router/cdrom/tmpdir/8=ro:/mnt/router/cdrom/tmpdir/7=ro:/mnt/router/cdrom/tmpdir/6=ro:/mnt/router/cdrom/tmpdir/5=ro:/mnt/router/cdrom/tmpdir/4=ro:/mnt/router/cdrom/tmpdir/3=ro:/mnt/router/cdrom/tmpdir/2=ro:/mnt/router/cdrom/tmpdir/1=ro:/mnt/router/etfw=ro 0 0 none /.etfw_changes tmpfs rw 0 0 none /selinux selinuxfs rw 0 0 /proc /proc proc rw 0 0 /proc/bus/usb /proc/bus/usb usbfs rw 0 0 /sys /sys sysfs rw 0 0 none /dev/pts devpts rw 0 0 none /dev/shm tmpfs rw 0 0 none /proc/sys/fs/binfmt_misc binfmt_misc rw 0 0 > > For information: unionfs doesn't have this bug. > > Then, I recommend you to use unionfs, until this problem is gone. There are two problems in unionfs :) : The version of unionfs full operational without bugs is the version 1.x and this version only work until kernel 2.6.18. The version of unionfs 2.x don't have all features that I need and worst, with 2.6.20 when I run wvdial I have a kernel crash. > > PS: In attach the patch for last aufs cvs version against kernel 2.6.20* > > What do you want to say? > If you have modified by yourself, please point it out. No, it's only a patch that simplify the task to builtin aufs 20070219 in kernel. Regards, Fernando Gomes ------------------------------------------------------------------------- Take Surveys.
