That doesn't work, since I'm not making any entry for them in
/etc/fstab and hence there is no entry for /bin,/sbin,/lib and /usr in
/etc/mtab.
Error as below:
mount: can't find /bin in /etc/fstab or /etc/mtab
mount: can't find /sbin in /etc/fstab or /etc/mtab
mount: can't find /lib in /etc/fstab or /etc/mtab
mount: can't find /usr in /etc/fstab or /etc/mtab
Then I tried appending entries for /bin,/sbin.. etc in /etc/mtab
manually ( copied verbatim from /proc/mounts) and then try unmounting:
echo "none /bin aufs rw,si=db66c080,xino=/tmp/xino,br:/bin=rw:/.mount/bin=ro 0 0
mount -o remount,ro,mod:/bin=ro /bin
It failed with the following error:
failure bad /proc/mounts 1
Thanks,
