It's used for creating dovecot-acl-list. Hmm. Looks like there are now
two places where Dovecot takes permissions from: dovecot-shared file and
the directory where it exists. If you set g+s to the dir too this error
goes away. I'll have to think a bit more what I'll do about this. Maybe
dovecot-shared file just could go away and only the dir permissions
would be used.
