| 2 | # name plus a df- prefix. Ensures that these special |
| 3 | # distro features remain set also for native and nativesdk |
| 4 | # recipes, so that these overrides can also be used there. |
| 5 | # |
| 6 | # This makes it simpler to write .bbappends that only change the |
| 7 | # task signatures of the recipe if the change is really enabled, |
| 8 | # for example with: |
| 9 | # do_install_append_df-my-feature () { ... } |
| 10 | # where "my-feature" is a DISTRO_FEATURE. |
| 11 | # |
| 12 | # The class is meant to be used in a layer.conf or distro |
| 13 | # .inc file with: |
| 14 | # INHERIT += "distrooverrides" |
| 15 | # DISTRO_FEATURES_OVERRIDES += "my-feature" |
| 16 | # |
| 17 | # Beware that this part of OVERRIDES changes during parsing, so usage |
| 18 | # of these overrides should be limited to .bb and .bbappend files, |
| 19 | # because then DISTRO_FEATURES is final. |
