civodul pushed a commit to branch master
in repository guix.

commit 89bbcc80d7a6867515ba1057c98accf41cbb9077
Author: Ludovic Court├Ęs <address@hidden>
Date:   Sat Dec 21 16:27:31 2019 +0100

    guix system: Honor the build options in 'delete-generations'.
    
    Until now, 'guix system delete-generations' would ignore OPTS; for
    example, it would not enable #:print-extended-build-trace? & co.,
    leading to suboptimal output.
    
    * guix/scripts/system.scm (process-command)[with-store*]: New macro.
    Use it for 'delete-generations', 'switch-generation', and 'roll-back'.
