Thanks for sharing. That could be a welcome change.

1. How does fakechroot fakeroot perform privileged operations like chown,
   mknod, accessing other's files, mounting, etc.?

   We need that information to be consistent across multiple commands in
   multiple recipes (bootstrap, customize, install stuff, deploy, etc.).
   Wrapping one command is probably possible with any tool -- but currently I
   don't see how they could do what we need.

   Regarding keeping the information across multiple commands, Yocto's pseudo
   should allegedly be able to do that (not sure whether it keeps the state in
   a daemon or a file). Evaluating that was our next step (very low prio ATM)
   -- maybe that could be interesting for you as well.

2. fakechroot fakeroot is reported to work with foreign-arch chroots. Have you
   tried that?

With kind regards,
Baurzhan.
