We recently ran into an issue where CTS was failing on property_contexts. The best I can tell, is that the CTS build had locale of en_US.utf8 while the local build had a locale of C which affected the sort ordering as sort respects locale.
I proposed a patch to use fc_sort, here: https://android-review.googlesource.com/#/c/platform/system/sepolicy/+/491917/ Which avoids the locale issue and strips comments so sed can dissapear. I see it also existing for property contexts, so likely want to submit a patch for that too. -- Respectfully, William C Roberts
