The flarcreate command no longer has size limitations on individual files. You can create a Solaris Flash archive that contains individual files over 4 Gbytes. The following two archive utilities are available for use:
The portable archive interchange utility, pax, is the default. The archive can be created without size limitations on individual files.
The cpio archive utility is invoked with -L cpio option. Individual files cannot be greater than 2 or 4 Gbytes. The size limitation depends on the version of cpio used. This option is useful for backward compatibility issues.
