mungkin maksudnya CDDL kompatibel dengan Open Source alias sudah disetujui OSI
sebagai lisensi Open Source, tetapi tidak kompatibel dengan GNU GPL.
Mas Iwan,
Maksud saya adalah, program dengan lisensi GNU/GPL bisa "masuk"
(kompatibel) di OpenSolaris, tapi lisensi CDDL tidak bisa "masuk" (tidak
kompatibel) di GNU/Linux.
Sebagai contoh, banyak aplikasi GNU/GPL yang ada di OpenSolaris, tapi
teknologi di OpenSolaris (yang berlisensi CDDL) tidak bisa "masuk" ke
GNU/Linux, seperti: ZFS, DTrace dsb.
Untuk lebih jelas-nya mungkin bisa dilihat disini:
http://en.wikipedia.org/wiki/DTrace dan http://en.wikipedia.org/wiki/ZFS
Saya quote-kan statement dari halaman tersebut di bawah ini:
Porting ZFS to Linux <http://en.wikipedia.org/wiki/Linux> is
complicated by the fact that the GNU General Public License
<http://en.wikipedia.org/wiki/GNU_General_Public_License>, which
governs the Linux kernel
<http://en.wikipedia.org/wiki/Linux_kernel>, prohibits linking with
code under certain licenses
<http://en.wikipedia.org/wiki/List_of_software_licenses#GPL_2_incompatible>,
such as CDDL <http://en.wikipedia.org/wiki/CDDL>, the license ZFS is
released under.^[30]
<http://en.wikipedia.org/wiki/ZFS#cite_note-kerneltrap-29> One
solution to this problem is to port ZFS to Linux's FUSE
<http://en.wikipedia.org/wiki/FUSE_%28Linux%29> system so the
filesystem <http://en.wikipedia.org/wiki/Filesystem> runs in
userspace <http://en.wikipedia.org/wiki/Userspace> instead. A
project to do this was sponsored by Google's Summer of Code
<http://en.wikipedia.org/wiki/Google_Summer_of_Code> program in
2006, and is in a bugfix-only state as of March 2009.^[31]
<http://en.wikipedia.org/wiki/ZFS#cite_note-fuse-30> The ZFS on FUSE
project is available here. <http://www.wizy.org/wiki/ZFS_on_FUSE>
Running a file system outside the kernel on traditional Unix-like
systems can have a significant performance impact
<http://en.wikipedia.org/wiki/Context_switch>.
Thanks and CMIIW :-)
