This refactors the code of
chcon
in order to reduce the number ofunsafe
blocks and keep them isolated.After this refactoring,
chcon
no longer depends directly on theselinux-sys
crate.Most remaining
unsafe
blocks relate to direct usage offts-sys
APIs. This usage is currently necessary in order to keep the behavior of ourchcon
similar to its GNU implementation.
