hi i was wondering about something..
poke me if it is in the guides and i havnt noticed.
for example.. i have some common USE flags in my make.conf so i feel comfortable with my system. but know i decided to have program x (e.g. apache) and of course i dont want to change my system wide USE flags if i want to support berkleydb in mod_php. so i do a
| Code: | | export USE="mod_php berkleydb" |
this is an example so dont punch me if there are some typing mistake. now after everyhting went fine (as always) everything is nice and i can open up my next can of beer. but now something terrible happens.. program x has a bug.. and some evil nerd made an ebuild 20 minutes after the fix and i really want to update as soon as possible. now the question:
what iis the appropiate way to upgrade the package?
| Code: | emerge rsync
emerge x
emerge clean |
or
| Code: | emerge rsync
emerge -u x |
and (this is the important part) what happens to the custom USE flags i entered while first installing the program? are they stored somewhere and reused? or do i have to figure it out again what i want to use?
would be nice if someone can clearify this a bit, thx. |

| Code: | | emerge rsync && emerge -C x && emerge x |
is the safe way
| Code: | | emerge rsync && emerge -u x |
is the fast way |

To answer your question: the custom USE flags are lost. Why don't you simply set the USE statement in /etc/make.conf to be what you want?

When there is a package being updated for security reasons, the announcements recommend: | Code: | emerge rsync
emerge some-package
emerge clean |

well yeah.. i could do them in make.conf.. but i dont want to..
i may want to compile a program with qt support for example but others not.. and changing make.conf all the time is a pain in *$%&%. ! 
and put 'berkleydb' into make.conf for just a special exception just doesnt seem right..
are we really lacking some flexibillity here?! |

| Perhaps this comment has been previously made, but would it not be great to be able to "pin" use flags to a package, similar to the way one might pin a specific version? |

Heya...
I think that this is already available... I am not exactly sure how this works as I have not tried it, however I would assume that on a clean install of the program (ie. emerge kdelibs) it would use your normal flags. On an update (emerge -u kdelibs) it would use the flags that it was previously installed with.
These flags themselves are recorded with every installed program in:
| Code: | | /var/db/pkg/pkg-tree/pkg-name |
So the information is recorded there.
As for the other...Another option, instead of exporting, is to do something like:
| Code: | | # USE="-gnome kde" emerge whatever |
This is something that I have done in the past and it works like a charm. Basically does the same thing as exporting, but only for the command that follows.
Hope that helps,
Justin T |
