|
|
# ADDITIONAL_GUIX_COMMON_FLAGS, but the value of GUIX_BUILD_OPTIONS is actually

|
# precedence over the command-specific ADDITIONAL_GUIX_<CMD>_FLAGS.
|

|
|
#
|
||
|
|
# This seems like a poor user experience. Thus we check for GUIX_BUILD_OPTIONS's

# existence here and direct users of this script to use our (more flexible)
|

GUIX_BUILD_OPTIONS and use ADDITIONAL_GUIX_COMMON_FLAGS to set build options
