 Posted: Fri Sep 27, 2019 2:50 am Post subject: [SOLVED] Automatic Use Flags per package |
 |
|
Good Evening All,
I haven't been on Gentoo for years - but am considering a return. SystemD continues to anger me. I am through with it. The USE flags and all the complexity they introduce caused me issues way back when. (in the stage 1 days)
So before I start with trial hardware - I have a question.
Is there a way to configure portage to automatically turn on the use flags a package supports, and disable flags they don't?
I'd like to do this at the system level so I don't have to stipulate USE flags on a per-package basis - rather, have the system handle it. For me, this will simplify things from a sys admin standpoint. Specifying USE flags got me in trouble before - so I'd like to manage them differently this time.
Thank you for any pointers/suggestions you can provide,
Respectfully,
dcbdbis

Well, there is kind of a minimum default use list when you select a profile, check
| Code: | | eselect profile list |
and decide what your system is used for.
And then you can install ufed package
| Code: | app-portage/ufed
Webpage: https://wiki.gentoo.org/wiki/Ufed
Description: Gentoo Linux USE flags editor
|
and use it to browse and set the use flags you really need. I would not try to enable all use flags a package offers, but only the ones you really need. All else is falling for featuritis.
The less use flags you use the lower the complexity / cross-dependencies. This is exactly the core of gentoo, you can and must choose what you want. And live with the consequences in terms of complexity then. |

Now portage tell you, after dependencies calculation, the use flags that need to be set with message like this
| Code: | # required by sys-libs/ldb-1.1.26::gentoo
# required by net-fs/samba-4.2.9::gentoo
# required by @selected
# required by @world (argument)
>=sys-libs/tevent-0.9.28 python |
after that you can use etc-update to write this change in relative /etc/portage/package.use file.
Anyway pay attention on that portage want to do

Welcome back to Gentoo dcbdbis  .
Portage's autounmask features can ease pushing required USE flags to a dedicated file, as well as unmasking packages to an alternate one if required.
etc-update allow to activate this changes before you emerge for real.
The con being these files turning to a mess quite quickly, IMHO.
This link might help.
If HW compatible don't forget about GCC_FLAGS_X86.
Declaring only 2 python, such as 2_7 & 3_6, then defaulting to the later, is likely will match your needs. especially if you're going stable.
Thks 4 ur attention. |

Thank you all for your suggestions. I appreciate the responses. I don;t want the world as far as features, now that I am retired - I just want solid functionality.
Again, thank you all.
Regards,
