I don't know much about amd64, so I don't know how the 'multilib' |
| 7 |
thing would work. But in so far as switching from a hardened profile |
| 8 |
to a non-hardened one and vice versa: the answer is yes and no. |
| 9 |
|
| 10 |
Going from hardened to non-hardened is generally easier, I think. |
| 11 |
The available packages from hardened is generally a subset of the ones |
| 12 |
from non-hardened. So once you switch profiles you'd be prompted to |
| 13 |
upgraded GCC and many other packages, and you'll find a few more (and |
| 14 |
possibly a few fewer) USE to work with. Most of these will fix itself |
| 15 |
over time. |
| 16 |
|
| 17 |
Going from non-hardened to hardened may run into some downgrading |
| 18 |
problems, however, in view of the above. For example, hardened devs |
| 19 |
still have not put gcc4 in stable (at least on x86, I don't know about |
| 20 |
amd64), so if you have gcc4 installed, you'll need to downgrade. Along |
| 21 |
the same lines some packages that will not compile unless you use gcc4 |
| 22 |
cannot be installed (lilypond for example). |
| 23 |
|
| 24 |
I suggest that you compare and contrast the package.mask and |
| 25 |
package.use.mask (and possibly make.defaults) files in the |
| 26 |
/usr/portage/profiles/{hardened,default/linux} directories to see what |
| 27 |
differences there are. |

|
| 32 |
Is emerge -e world even necessary? (Someone correct me if I am wrong.) |
| 33 |
My understanding is that switching profiles between hardened and |
| 34 |
non-hardened does not cause such drastic change to the toolchain that |
| 35 |
you must rebuild everything now. I am pretty sure when I switched my |
| 36 |
desktop to hardened I just let it gradually phase in. |
