Hi,
I upgraded (in place upgrade, preserving my dovecot configs) to a newer
release of ubuntu in order to gain access to slightly newer Dovecot
release and be able to use Dsync for migration from Cyrus, here is my
doveconf -n output:
# 2.1.7: /etc/dovecot/dovecot.conf
# OS: Linux 3.5.0-44-generic x86_64 Ubuntu 12.10
auth_debug = yes
auth_default_realm = whatever.com
auth_master_user_separator = *
auth_socket_path = /var/run/dovecot/auth-master
imapc_features = rfc822.size
imapc_host = oldmail.whatever.com
imapc_master_user = cyradmin
imapc_password = <password hidden>
mail_chroot = /var/vmail
mail_debug = yes
mail_gid = 5000
mail_location = maildir:~/Maildir
mail_prefetch_count = 20
mail_privileged_group = vmail
mail_uid = 5000

passdb {

}
passdb {

}
plugin {
sieve = ~/.dovecot.sieve
sieve_dir = ~/sieve
}
protocols = " imap lmtp sieve pop3"
service auth-worker {

}
service auth {

}

}
}
service lmtp {

}

}

userdb {

}
protocol lmtp {
postmaster_address = p...@whatever.com
}
protocol imap {
mail_max_userip_connections = 10
}
protocol pop3 {
pop3_uidl_format = %v.%u
}
And the command I am using to (attempt) a mailbox sync:
doveadm -o mail_fsync=never backup -R -u alantestu...@whatever.com
imapc:
Produces this output:
dsync(alantestu...@whatever.com): Error: user
alantestu...@whatever.com: Couldn't drop privileges: getgrnam(vmail)
failed: No such file or directory (in mail_privileged_group setting)
dsync(alantestu...@whatever.com): Fatal: User init failed
mail.log shows this:

I followed this doc (which could use a little fleshing out, I will be
happy to do it once I get a grasp on this!):

Thanks in advance!
