 Posted: Fri Jul 11, 2008 3:47 pm Post subject: Switching profiles... |
 |
|
Some time back, when I had to upgrade my profile (the one I was using was deprecated), I decided to try the server profile (default-linux/amd64/2007.0/server)...
Well, now that 2008 is out, and the profile layout has changed, I'd like to go ahead and switch profiles back to the standard default/linux/amd64/2008.0
My question is, whats the easiest way to compare the current USE flag settings, to what they will be using the new profile... in other words, is there a command I can type that outputs my current profile USE flag settings, that I can then use to make sure my new profile duplicates them?
tia... |

libertytrek,
Use | Code: | eselect profile list
eselect profile set X |
to see and change profiles.
will list your USE flags as set in the selected profile and make.conf.
It will not list settings in /etc/portage/package.use.
Note that /2008.0 is intended to be a parent profile and not used directly.
Its OK to use it directly if you want, you just need more settings in /etc/make.conf

Hi NeddySeagoon (what is a neddyseagoon?) 
Yes, I'm aware of eselect, and I was also aware of emerge --info, just had a brain gorp...
As for /2008.0 not being intended to be used directly...
I guess I could just continue to use /server... it *is* a server, but I'm not comfortable with using a hardened profile... especially not converting an existing non-hardened profile to a hardened one (if this is recommended or even possible)... |

This answers your first question.
You can turn off all the flags in your profile if you like by using the special USE flag -*
That gives you full control in make.conf
Its not just the profile that changes for a hardened system. You need a hardened gcc, glibc, kernel and a rebuild of all your applications.

Heh... figured it was something like that... I was trying to remember if it was a Monty Python thing...

Hmmm... sorry if this is a dumb question, but would I be right to say that a profile is just a pre-defined set of USE flags?

Right... nnd you need to decide which method to implement (SELinux, RSBAC, etc)... its just over my head right now, and I don't have the time to devote to learn what is necessary... someday maybe... |

libertytrek,
Your profile is a lot more than a collection of predefined USE flags.
It sets your default arch, package.mask, package.provided and a few other things
They are all thisngs that can be fine turned in /etc/portage/*
See
All the files in your profile are text files - read them. They are also hierarchal as you traverse the directory structure,
so 2008.0/server inherits whatever is in /2008.0 and so on

Ok, guess its time to do some reading... but for now I think I'll just upgrade to /2008.0/server...
Thanks again.... |

That was very useful to actually do.. I'd never gone to the bottom of the profile hierarchy and just repeatedly cd ..'d, reading misc files, ls'ng and less'ing interesting dir contents along the way. Always gotten tangled in the various parent paths and figured it wasn't worth untangling, gone off to eselect different profiles and compare emerge --info diffs (which are hard to read). Thanks for making things simpler again Sr. Seagoon. |
