Running 2.10.2 on 4.3BSD, I have found out that when a posting was
done to a newsgroup whose directory was not there yet, it was created
owned by the poster, rather than 'news'; this prevented 'news' from
creating any articles in it. It seems that rnews tries to work in the
poster's uid rather than use its suid.

This 'should not have happened' since each new group is created with its
directory, but in one of the latest newsgroup rushes, mkdir sometime
failed - it tried to create all groups at once, forking 'inews -C' for
each, which sometimes tried to mkdir 'a/b' before 'a' was done.

I have noticed that in 2.11, 'checkgroups' is rush-proof since it only
tells you what to 'inews -C'; but is the suid behaviour described above
a bug or a feature? was it fixed in 2.11? (I'm not waiting for the next
rush to find out).
