Bug#35568: apt keeps complaining about dpkg's post-invoke

[Linh Dang <linhd@nortelnetworks.com>]

Package: apt
Version: 0.3.3

when I install with apt, I keep getting this error message after dpkg
finished installing everything:

 mount: /usr is busy
 E: Problem executing scripts DPkg::Post-Invoke 'mount -o remount,ro /usr'
 E: Sub-process returned an error code

My /etc/apt/apt.conf is:

 DPkg 
 {
     // Auto re-mounting of a readonly /usr
     Pre-Invoke {"mount -o remount,rw /usr";};
     Post-Invoke {"mount -o remount,ro /usr";};
 }
                           
I type 'mount -o remount,ro /usr', the mount is successful.

My system:

 Package: dpkg
 Version: 1.4.1.1
 
 Package: libc6
 Version: 2.1.1-0.1
 
 Package: libstdc++2.9-glibc2.1
 Version: 2.91.63-1.1
