>Description:
You cannot build a port as root using an NFS-mounted /usr/ports if the
server maps root to a UID other than root. When extracting the
source, tar thinks that it is root and attempts to chown the files
that it extracts to the owner in the tar file. The chown fails,
tar fails and thus the build fails.
>How-To-Repeat:
Mount /usr/ports on a client from a server with the following in
/etc/exports:
/usr/ports -maproot=ports:src
(where the ports directory tree is writeable by ports:src). From a
client machiine, mount /usr/ports over NFS then choose any port and do
(as root):
make EXTRACT_PRESERVE_OWNERSHIP=yes extract
It will fails with messages that tar cannot change ownership of the
files that it extracts. (EXTRACT_PRESERVE_OWNERSHIP needs to be
defined to prevent bsd.port.mk from chowning the extracted tree to
root).
>Fix:
Put tar's attempt to change ownership under control of the same
EXTRACT_PRESERVE_OWNERSHIP variable:
