While upgrading my ports from 12.0-RELEASE to 12-STABLE, I encountered a lot of Text file busy errors, and almost no ports I could update successfully. Then I attempted to fix/workaround the issue, and finally I found that r348991 Switch to use shared vnode locks for text files during image activation broke my uinonfs, which was the culprit for Text file busy issue. https://svnweb.freebsd.org/base?view=revision&revision=348991 I filed the issue in Bugzilla. Someone please look at the issue. https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239100 P.S. For freebsd-current, r348991 was MFC r347151,347181,347968,348421,348698,348701 . -- UEMURA, Tetsuya <t_uemura at macome.co.jp>
