There were many fixes in this area lately. The case where a file system with softdeps would fail to update to read-only is fixed in -CURRENT and these changes are merged to -STABLE. It is believed to work correctly. http://lists.freebsd.org/pipermail/freebsd-stable/2008-October/046001.html Remounting with soft updates enabled used to be too fragile to be useful. Now it seems very solid. Nikos
