Hi, Here's what "gcj-dbtool --rebuild" needs to do: Merge all db files in "$prefix/lib/gcj-$gcc_version/classmap.db.d/" into "$prefix/lib/gcj-$gcc_version/classmap.db". Even better for FC5 would be eliminating the need for individual .db files altogether. We could have "gcj-dbtool --rebuild" compare the .sos in /usr/lib with the database contents and add/remove any new/missing entries to/from classmap.db. Shipping a .db file per package is one divergence from JPackage spec files that Fernando's proposal doesn't address but that an improved gcj-dbtool would. Tom
