Description Zac Medico gentoo-dev 2019-02-18 21:44:22 UTC
ACCEPT_LICENSE has support for things like "* -@EULA" which do not follow the usual incremental variable behavior. Since it has a different implementation, ACCEPT_LICENSE settings in profiles are not incremental with respect to each other, but ACCEPT_LICENSE settings in make.conf are incremental with respect to the profile setting.
Comment 1 Zac Medico gentoo-dev 2019-02-18 21:49:02 UTC
Given the deviance in behavior from usual incremental variables, I recommend that profiles do something like this if they want incremental like behavior:

Thanks, this saved my day :)
Comment 3 Ulrich Müller gentoo-dev 2019-04-16 11:24:43 UTC
PMS defines incremental variables in section 5.3.1:

"Other variables, except where they affect only package-manager-specific functionality (such as Portage’s FEATURES variable), must not be treated incrementally—later definitions shall completely override those in parent profiles."

So from a PMS point of view either behaviour would be fine.
