Running poudriere on another most recent CURRENT box with a 13-STABLE jail also 
gives me the
ability to build a clean 13-STABLE jail (buildworld from sources from another 
source tree like
it is done for FreeBSD-pkgbase, then updating jail's with poudriere's -m
src=/path/to/13-STABLE/src) - the only pity is that due to a chflags problem 
during install I
have to delete the jail first and then recreate it to install the new compiled 
13-STABLE
binaries. Quint essence: Since a couple of weeks for now I can build 13-STABLE 
on CURRENT that
way. But I can't build NanoBSD as reported above.
