tar.bz2 is a tar archive compressed with bzip2. pkg.bz2 is _probably_ an SVR4 pkg datastream file (format is derived from cpio), compressed with bzip2. pkg files are installed with the pkgadd command.
I would usually prefer pkg (old) or IPS (new packaging system) packaged software, rather than simply archives that one extracts, because then the system will keep track of what's installed. But sometimes, such as if I want to have more than one version of something installed, I might use the tar archive instead. It depends on whether the software has to be installed in a specific location (so that the parts of it can find each other using hard-coded paths), or whether it will work wherever you put it. Installing multiple versions usually works out better if they're able to be installed anywhere, so that they don't need to go in the same place. -- This message posted from opensolaris.org _______________________________________________ opensolaris-help mailing list opensolaris-help@opensolaris.org
