If you have a separate /var dataset in a previous Solaris 10 release and you want to use luupgrade to upgrade to the Solaris 10 10/09 release, and you have applied patch 121430-42 (on SPARC systems) or 121431-43 (on x86 systems), apply IDR143154-01 (SPARC) or IDR143155-01 (x86) to avoid the issue described in CR 6884728. Symptoms of this bug are that entries for the ZFS BE and ZFS /var dataset are incorrectly placed in the /etc/vfstab file. The workaround is to boot in maintenance mode and remove the erroneous vfstab entries.
