Changing to the cascaded profile

[JoseJX]

Since portage 2.0.51 has been marked stable on ppc, we now have the ability to use cascaded profiles. For a more in depth explanation of cascaded profiles, see here, but basically, cascaded profiles make maintence of the profiles (default settings and other important stuff) a whole lot easier. The issues we've been seeing with pam and the recent virtual/fam issues would not have occurred had we been using the cascaded profiles. Since we will be transisitioning to the cascaded profile, now would be a great time to switch!

So, you may ask, how does one go about changing their profile to the cascaded profile? Easy!

Great! Thanks!
I'll give it a try tonight.

ok, but when using the cascaded profile, 'emerge -p depclean' wants to remove tons of apps, most of which come from 'emerge system'.... I can remember 'yaboot' for instance... Back to the normal profile for now ;)

EDIT: ok, I'll try to make this message more useful... Using the normal profile, 'emerge -p depclean' has no candidate for removal, which is normal. Now, if I switch to the cascaded one, here's what it wants to remove :

sys-apps/slocate
net-misc/dhcpcd
app-arch/sharutils
sys-apps/powerpc-utils
sys-apps/setserial
sys-boot/yaboot
sys-apps/fbset

voilà... hope it helps you fixing it :)

The profile doesn't need to be fixed, those apps now have to be installed manually since they're not part of a bare working system. Yaboot and powerpc-utils don't make much sense on a pegasos box. sharutils, setserial, slocate, fbset and dhcpcd are not required apps for a running system, so they were removed. For the "not required" apps, we're inheriting the choices made by the rest of Gentoo (one of the great features of the cascaded profiles!), but the ppc specific apps are our choice. An emerge system should really only include the applications required for basic system operation and dropping these apps are part of an attempt to give the user more flexibility.

I will add an instruction to emerge the above pacakges when switching the profile, thanks for the feedback!

When I made this conversion and try "emerge -p depclean', the script uninstalled attr and acl. I don't considere this important, but when the depclean erase this packages, my gentoo stop working.
I coultdn't re-emerge the packets or run some standar apps (like a simple 'ls'). I realised my error, the depclean delete some very important shared libs: libacl and libattr.

I have reinstaled the libs using the livecd and some ppc.rpms (thanks rpm2targz xD) and I'm instaling the acl and attr again without problems.

Only a note for stupid users like me

Heya guys,

I switched to the cascading profiles and so far it all went very smooth. Out of curiosity I did a

Usually, a new profile is only added when there is a new release. Changing it mostly only changes a new installation. You'll be notified by portage when the particular profile that you're using is depreciated (and slated for removal).

However, because of the recent addition of cascaded profiles we're recommending that you switch to the new one. This change is actually less likely to occur in the future because of the way cascading profiles can inherit properties.

So to sum all that up: No, you do not need to change your profile whenever a new one is available. :)

I've changed to the cascaded profile using

I assume that we should use a link to /usr/portage/profiles/default-linux/ppc64/2004.3 for a G5. Is it correct?
