[Bug 1908818] Re: pure packaging of libnss3

[Christian Ehrhardt ]

** Description changed:

+ [Impact]
+ 
+  * A packaging error in the current version has led library symlinks
+    to be broken and in the wrong place.
+ 
+  * Fix by applying the later change to Groovy as well
+ 
+ [Test Plan]
+ 
+  * install libnss3
+  * check (path depends on the architecture) the lib links
+    $ dpkg -L libnss3 | grep MULTIARCH
+    # ^^ should be empty
+    $ ll /usr/lib/x86_64-linux-gnu/libfreebl3.so
+    # vv should look like that:
+ 
+ lrwxrwxrwx 1 root root 17 Feb 16 15:18 /usr/lib/x86_64-linux-gnu/libfreebl3.so -> nss/libfreebl3.so
+ root at h:~# ll /usr/lib/x86_64-linux-gnu/libfreebl*
+ lrwxrwxrwx 1 root root 18 Feb 16 15:18 /usr/lib/x86_64-linux-gnu/libfreebl3.chk -> nss/libfreebl3.chk
+ lrwxrwxrwx 1 root root 17 Feb 16 15:18 /usr/lib/x86_64-linux-gnu/libfreebl3.so -> nss/libfreebl3.so
+ lrwxrwxrwx 1 root root 22 Feb 16 15:18 /usr/lib/x86_64-linux-gnu/libfreeblpriv3.chk -> nss/libfreeblpriv3.chk
+ lrwxrwxrwx 1 root root 21 Feb 16 15:18 /usr/lib/x86_64-linux-gnu/libfreeblpriv3.so -> nss/libfreeblpriv3.so
+ 
+ [Where problems could occur]
+ 
+  * I first was afraid, that no matter how bad the paths would
+    have been we'd need to retain them for anyone using them
+    already. But the existing links go into nowhere since they
+    are relative therefore the regression risk should be minimal
+ 
+ root at g:~# ll '/usr/lib/${DEB_HOST_MULTIARCH}/libfreebl3.so' '/usr/lib/${DEB_HOST_MULTIARCH}/libfreeblpriv3.so' '/usr/lib/${DEB_HOST_MULTIARCH}/libfreebl3.chk' '/usr/lib/${DEB_HOST_MULTIARCH}/libfreeblpriv3.chk'
+ lrwxrwxrwx 1 root root 18 Sep 29  2020 '/usr/lib/${DEB_HOST_MULTIARCH}/libfreebl3.chk' -> nss/libfreebl3.chk
+ lrwxrwxrwx 1 root root 17 Sep 29  2020 '/usr/lib/${DEB_HOST_MULTIARCH}/libfreebl3.so' -> nss/libfreebl3.so
+ lrwxrwxrwx 1 root root 22 Sep 29  2020 '/usr/lib/${DEB_HOST_MULTIARCH}/libfreeblpriv3.chk' -> nss/libfreeblpriv3.chk
+ lrwxrwxrwx 1 root root 21 Sep 29  2020 '/usr/lib/${DEB_HOST_MULTIARCH}/libfreeblpriv3.so' -> nss/libfreeblpriv3.so
+ 
+  * never the less, to be clear - if problems occur they would be in 
+    loading these libraries. E.g. a user could have had this package
+    and a self built nss on his system, after the change it might load the 
+    packaged one.
+ 
+ [Other Info]
+  
+  * n/a
