A mechanism that enables automatic data sharing across different boot environments is available from Oracle Solaris 11.1 release. These shared directories are stored in the rpool/VARSHARE file system that is mounted at /var/share. Placement of shared data in the /var directory reduces the amount of space needed for all boot environments.
# ls /var/share audit cores crash mail
The /var/share file system generally requires no administration, with the exception of ensuring that the /var components do not fill the root file system.
Symbolic links are automatically created from /var to the /var/share components listed above for compatibility purposes. For more information, see datasets (5) .
