Dovecot 2.4 USE flag - SOLVED

[jankom]

I had a working mail server, but with dovecot update ferm 2.3.x to 2.4.2-r2 I need to make serious configuration adjustments. I follow https://wiki.gentoo.org/wiki/Complete_V ... d_Packages
My dovecot was compiled without USE flag either for mysql or postgres. Presently I have sqlite in my system.
My question is should I use a global use flag configured in make.conf as instructed or just set the USE flag specific for dovecot? I could ask why the instruction suggests the make.conf change? I'm concerned about potential conflict between sqlite and postgres.

There shouldn't really be any conflict, since you still have to configure your servers to actually use your database of choice. This said, if you only need it for mail, then by all means enable it only for dovecot and postfix. They both need it.

And the suggestion to change make.conf is probably just old, it used to be the default way of customizing our systems. I personally still like it, because "if I already have it as a dependency, I might as well use it as much as possible". There's nothing inherently wrong with the new approach though, do whichever makes the most sense at the moment.

I understand. I installed Gentoo 5 years ago, and my original make.conf file was very basic, quoted here:
# These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /usr/share/portage/config/make.conf.example for a more
# detailed example.
COMMON_FLAGS="-O2 -pipe"
CFLAGS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS}"
FCFLAGS="${COMMON_FLAGS}"
FFLAGS="${COMMON_FLAGS}"

# NOTE: This stage was built with the bindist Use flag enabled
PORTDIR="/var/db/repos/gentoo"
DISTDIR="/var/cache/distfiles"
PKGDIR="/var/cache/binpkgs"

# This sets the language of build output to English.
# Please keep this setting intact when reporting bugs.

I since made adjustments, but apply USE flags in the package.use file. But I understand your point. Still debugging my mail server following Gentoo instructions. Will close this topic when I succeed.
