[Bug 942940] [NEW] precise base-files /var/run migrate_dir fails on pkg configure

[Tom Gall]

Public bug reported:


Using precise, multistrap and live-build to build Linaro images, we have noted the following bug in base-files.  In debian/postinst.in on line 26 we have


     26 migrate_directory() {
     27   if [ ! -L $1 ]; then
     28     rmdir $1
     29     ln -s $2 $1
     30   fi
     31 }


Note that due to multistrap later on in this same file line 55, will fail cause when the dpkg --configure -a step happens /var/run already exists and is not certain to be empty causing rmdir to fail.. 

     54   install_directory run/lock 1777 root
     55   migrate_directory /var/run /run


The directory as part of the configure step can be safely blow away. Thus the fix recommended is :

     26 migrate_directory() {
     27   if [ ! -L $1 ]; then
     28     rm -rf $1
     29     ln -s $2 $1
     30   fi
     31 }

Please apply.
