If the disk + was opened for writing, the close will trigger a partition + table rescan in udev's "watch" facility, and if needed + synthesize "change" events for the disk and all its partions. + This is now unconditionally enabled, if it turns out to + cause major problems, we might turn it on only for specific + devices, or might need to disable it entirely. Device-mapper + devices are excluded from this logic. + CHANGES WITH 213: * A new "systemd-timesyncd" daemon has been added for diff --git a/configure.ac b/configure.ac index 3252e65c98..4ba0abf49b 100644 --- a/configure.ac +++ b/configure.ac @@ -34,7 +34,7 @@ AC_USE_SYSTEM_EXTENSIONS AC_SYS_LARGEFILE AC_PREFIX_DEFAULT([/usr]) AM_MAINTAINER_MODE([enable]) -AM_INIT_AUTOMAKE([foreign 1.11 -Wall -Wno-portability silent-rules tar-pax no-dist-gzip dist-xz subdir-objects check-news]) +AM_INIT_AUTOMAKE([foreign 1.11 -Wall -Wno-portability silent-rules tar-pax no-dist-gzip dist-xz subdir-objects]) AM_SILENT_RULES([yes]) AC_CANONICAL_HOST AC_DEFINE_UNQUOTED([CANONICAL_HOST], "$host", [Canonical host string.]) |
