Hi
When we choose a profile during the installation do we also choose some invisible use flags?

In the /etc/portage/make.conf file initially there were a few flags (or one flag only I don't remember which had one flag only and which had few flags because I'm trying installations on 2 different computers one 32 bit and the other 64 bit)

What led to me to this thought is that I saw when installing xorg:

Code:
# emerge -pv xorg-drivers

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ]  x11-base/xorg-drivers-1.9  INPUT_DEVICES="evdev synaptics
-acecad -aiptek -elographics% -fpit% -joystick -keyboard -mouse -penmount -tslib

Profiles may setup some use flags (http://wiki.gentoo.org/wiki/Profile), however each ebuild can be given an IUSE as is the case of Xorg (http://devmanual.gentoo.org/ebuild-writing/eapi/index.html).

Profiles are stored into the profile subdir in the portage directory (usually /usr/portage/profiles). Just taking a look at the files in there should enlighten you.
