Sounds interesting... but something I must be doing wrong here: $ rebase --oblivious --filelist=my-dlls.txt local-test-rebase-db local-test-rebase-db: skipped because nonexistent. $ touch local-test-rebase-db $ rebase --oblivious --filelist=my-dlls.txt local-test-rebase-db local-test-rebase-db: skipped because not rebaseable $ cp /etc/rebase.db.x86_64 local-test-rebase-db $ rebase --oblivious --filelist=my-dlls.txt local-test-rebase-db local-test-rebase-db: skipped because not rebaseable It doesn't want to create or update the local-test-rebase-db file...
