Alas SMACK support hasn't been properly regression tested since the Tizen guys wandered off about 5 years ago. I don't have a test environment for it. (Can you maybe suggest a distro I can run in kvm to test it?) In theory we're preserving the xattrs so the security context should marshall along. I admit some of the newer code (ala tar) has specifically thought about selinux rather than using the generic lib/lsm.h wrapper functions just because nobody'd asked about smack in so long. > This is the command I run, > > cp -a --preserve=all --parents <abs path to source file or folder> > <destination > directory> > > What I see is that the final file has the correct SMACK attributes, but the > intermediate folders have their SMACK labels reset to "System".

Ah, that's a known issue: https://github.com/landley/toybox/blob/0.8.10/toys/posix/cp.c#L273 Hmmm, I'll take another stab at it...
