[PATCH] D93881: [llvm-objcopy] preserve file ownership when overwritten

[Robert Underwood via Phabricator via llvm-commits]

robertu94 added a comment.

I could be wrong (@mgorny would know better), but it was my understanding that portage (if `sandbox` and `userpriv` FEATURES in are set in make.conf on not overwritten from /usr/share/portage/config/make.globals) drops user privileges to the `portage` user and group using the `setuid`/`setgid` functions during the unpack, prepare, configure, compile, and test phases.  During the install process `fakeroot` can be used (but not the default), but I don't believe that privileges can be dropped separately from `fakeroot`.
