Hi curaga. I'm not sure if still marked "experimental" today. But I and others have tested these chipsets and they among the few that are stable enough on linux to recommend without reservations. The driver is already provided by wireless-KERNEL.tcz. Only users trying to use these chipsets would be affected if these config options were enabled.
Hi Juanito. Absolutely. That's not what /usr merge is about. The merge is about:
* eliminating /bin (which becomes a symlink to /usr/bin)
* eliminating /lib (which becomes a symlink to /usr/lib)
* eliminating /sbin (which becomes a symlink to /usr/sbin)
/usr/local and everything under it would be unaffected.
/usr merge simplifies the file system, leads to fewer broken absolute paths (for example, an application can look for either /bin/foo or /usr/bin/foo and both would work) and would increase compatibility between applications and TCL in the long run.
All that being said, TCL is already the best distro as-is. This would be a minor upgrade.
