[Dovecot] multi-instance doveadm user -m woes +WORKAROUND

Some more investigation yielded this solution:

[root at wardentest3 conf.d]# doveadm -c /etc/dovecot/mailtest/dovecot.conf user -m warden
field	value
uid	73464
gid	1000
home	/home/warden
mail	maildir:/Mail/mailhome/warden/mailtest/Maildir:CONTROL=/Mail/mailhome/warden/mailtest/.dovecot-control:INDEX=/Mail/mailhome/warden/mailtest/.dovecot-index

[root at wardentest3 conf.d]# doveadm -c /etc/dovecot/dovecot.conf user -m warden
field	value
uid	73464
gid	1000
home	/home/warden
mail	maildir:/Mail/mailhome/warden/Maildir:CONTROL=/Mail/mailhome/warden/.dovecot:INDEX=/var/cache/dovecot/mailtestindexes/warden/.dovecot-index

So it seems to be a problem with the -i flag to doveadm.

I should note that neither -c or -i show up in my man pages or in the wiki. I'm always nervous about making changes to the wiki (especially if I'm unsure if something is a 2.1+ feature), but it would be nice to see these flags documented somewhere…
