 ==== Fixing database problems ====
-You can't just do '''rm -rf /var/lib/rpm/%%__db*%%''' to fix problems anymore, also **--rebuilddb** is largely obsolete in rpm 5 and isn't likely to "fix" anything. Instead do:

 ==== Querying database ====
-The semantics of rpm query option **-f** (**--file**) has changed in rpm 5.x; '''rpm -q -f <file-with-path>''' will **not** resolve all symlinks in queried file's path. So the query (assuming ///usr/src/linux// is a symlink to ///usr/src/linux-A.B.C-R//):

@@ Line 42: / Line 61: @@
 It appears to be some type of a bug in the BerkleyDB 5.3.x.  In an attempt to workaround the problem, when we encounter this situation we attempt to adjust the size of the mmap buffer until the call works, or we end up trying 10 times.
 If DBI debugging is enabled, additional diagnostics are printed, otherwise a basic retry and success message is added to show that the failure was resolved.
+==== poldek: filesystem marks FHS (cap //) ====
+<code>
+# poldek -u filesystem
+Processing dependencies...
+filesystem-4.0-1.x86_64 obsoleted by filesystem-4.0-26.x86_64
+filesystem-4.0-26.x86_64 marks FHS-2.3-35.x86_64 (cap //)
+error: FHS-2.3-35.x86_64: equal version installed, give up
+</code>
+To fix, upgrade poldek, and invoke ''%%poldek --clean-all%%'', as the stored poldek indexes are invalid.
