For a number of chroot operations (e.g. building), mock uses an 
unprivileged user it creates in the chroot. By default, the uid/gid for 
this unprivileged user is chosen based on the user running mock (it 
looks at env data from sudo/consolehelper to determine the real user).

So, the builddir in the chroot is going to be owned by that unprivileged 
user. If you run mock as a /different/ user later and attempt to reuse 
the same buildroot, then you will get the errors like the ones you are 
seeing.

Short answer: different mock users cannot share chroots.

Easy fix: run mock clean to clear the old junk out of the buildroot.
