Note that rsync can be told to preserve extended file attributes (option
- -X). Whether that succeeds will depend, of course, on whether the target
file system can digest that.

Likewise, tar has an --xattrs option.

Capabilities and SELinux labels seem to be implemented on top of
xattrs (Disclaimer: I barely know what I'm talking about, but I
Looked It Up On The Internet(TM)). So all seems well here.

"By hand" sounds a bit sadomasochistic. I'd use -X resp. --xattrs
and sift carefully through warnings and errors. Plus perhaps check
one file or three to catch some systematic error.
