That's odd. I resubscribed with the new list domain.

mythvideo is not installed, and the only version showing in aptitude is
0.24.

By the way, does the 0.24->0.25 upgrade process leave a backup of the
0.24 database anywhere?

I notice some other activity at the same time as the myth upgrade. This
does create the messagebus user; perhaps that somehow had something to
do with the owner of mysql.text becoming messagebus (?). I'm not sure
if useradd will leak from the chroot to the main system, or conversely
if the host systems user info somehow gets into the chroot.

Host system:
messagebus:x:101:104::/var/run/dbus:/bin/false
bind:x:102:111::/var/cache/bind:/bin/false
mythtv:x:999:999::/var/lib/mythtv:/bin/sh

chroot:
mysql:x:101:102:MySQL Server,,,:/var/lib/mysql:/bin/false
mythtv:x:999:999::/var/lib/mythtv:/bin/sh
messagebus:x:102:105::/var/run/dbus:/bin/false

So mythtv is the same in both (I manually created it in the host to be
sure that was true) and messagebus is not. But it doesn't look as if
any confusion could cause mythtv to be mistaken for message bus.

Maybe something in the name resolution got messed up with mDNS?

Finally, /etc/hostname is corn-testing in the chroot, but when the host
syslog records messages from the chroot they are identified as corn.

Here are high points of syslog from the upgrade:
