+Subject: [PATCH hurd 06/11] trans/magic: convert to trivfs dynamic classes and
+ buckets
+
+libtrivfs contains two ways of managing more than one port class and
+bucket.  There is the old way of using a statically allocated array
+with explicit length, and the new way with dynamically allocated
+vectors.
+
+Converting all users to the new way of handling multiple classes
+and/or buckets, we can simplify the code in libtrivfs.  In many cases,
+the code will be simpler and more expressive for the user.
+
+This also fixes a severe bug.  As no classes are given to
+`trivfs_startup', they are created and inserted into the dynamic
+vector of classes.  The server function `trivfs_S_fsys_forward',
+however, used the first item of the previously used static array,
+which is NULL.  This circumvented the typecheck.
+
+* trans/magic.c: Convert to dynamic classes and buckets.
