Public bug reported:
Binary package hint: dpkg
Upgrade (or migration) from a directory to a link is resulting in an
empty directory instead of a symlink.
I have the following files in my install tree :
====
debian/tmp/usr/lib/foo/bar1/file1
debian/tmp/usr/lib/foo/bar1/file2
debian/tmp/usr/lib/foo/bar2/file3
....
====
I also have the following debian/foo.install dh_helper file:
=====
debian/tmp/usr/lib/foo/bar1
debian/tmp/usr/lib/foo/bar2
=====
I build and install the deb, all is good.
Now I decide to move /usr/lib/foo/bar1 to /usr/share/foo/bar1 and keep
only a link in /usr/lib/foo (so that the application continues to work).
I change debian/foo.install to:
====
debian/tmp/usr/lib/foo/bar1 usr/share/foo
debian/tmp/usr/lib/foo/bar2
====
and I add debian/foo.links with:
====
usr/share/foo/bar1 usr/lib/foo/bar1
====
I build, look at the deb using dpkg -c foo*.deb, it looks fine (files and link).
Now I install that deb.
I get /usr/share/foo/bar1 correct but /usr/lib/foo/bar1 is an empty directory
instead of the expected symlink that I can see in the deb.
/usr/lib/foo/bar2 is correct, as is everything else.
================
I've got that situation many times before (firefox, xulrunner, seamonkey,
prism, kazehakase, ..), here is xulrunner-1.9
when I've moved the plugins dir from /usr/lib/xulrunner-1.9b1/plugins to
/usr/lib/xulrunner-addons/plugins:
ix:~/bzr/build-area$ dpkg -c ./xulrunner-1.9_1.9~b1+nobinonly-0ubuntu1_i386.deb
| grep plugin
drwxr-xr-x root/root 0 2007-11-20 23:49

ix:~/bzr/build-area$ ls -ld /usr/lib/xulrunner-1.9b1/plugins
drwxr-xr-x 2 root root 4096 Nov 20 23:54 plugins/
To solve that, I have to either remove the package 1st or remove the
empty dir afterwards and force a re-install.
