dovecot - Sep 2012 - FTS indexing

I'm reacreating all FTS indices on all my users' INBOX folders:

mkdir ~%s/Maildir/lucene-indexes && chown %s:users
~%s/Maildir/lucene-indexes
doveadm index -u %s -q INBOX

In "ps auxwww" I'm seeing this:

tbudkevy 29186  3.7  0.0   6616  3056 ?        S    18:11   0:15
dovecot/indexer-worker [tschuetz INBOX]

how can a dovecot/indexer-worker actually access the INBOX of the
user "tschuetz" (where "tbudkevy" doesn't have access,
due to the
different UID)...?

Should ~%s/Maildir/lucene-indexes be filled after having run the command
sequence for all users?

You shouldn't need to do this. It's created automatically. Also by
"recreating" do you mean that the users already had Lucene indexes and
you deleted them?

indexer-worker runs basically as chroot, but it doesn't bother switching
back to root immediately. My guess is that this was a very brief race condition
in ps between reading process's UID and the command line. Unless you can
easily reproduce this?

Only if there was something in the INBOX. Also if users already had previous
Lucene indexes it doesn't work, you need to run doveadm fts rescan because
dovecot.index remembers which message was last indexed to Lucene.
