Here's my feeble attempt at diagnosing this:
****
mythbuntu-control-centre_0.10-0ubuntu1_all.deb is not the smoking gun, but it
does contain the following in
data/usr/share/pycentral/mythbuntu-control-centre/site-packages/MythbuntuControlCentre/changer.py:
def write_mysql_txt(self,user,password,database,server):
"""Writes out a mysql.txt in /etc/mythtv"""
if os.path.exists("/etc/mythtv/mysql.txt"):
print "Moving /etc/mythtv/mysql.txt to
/etc/mythtv/mysql.txt.mythbuntu-old"
shutil.move("/etc/mythtv/mysql.txt",
"/etc/mythtv/mysql.txt.mythbuntu-old")
out_f = open("/etc/mythtv/mysql.txt", "w")
out_f.write("DBHostName=" + server + "\n")
out_f.write("DBUserName=" + user + "\n")
out_f.write("DBName=" + database + "\n")
out_f.write("DBPassword=" + password + "\n")
out_f.close()
This snippet does not appear to set the mode of the file at all, so that it
inherits the permissions from /etc/mythtv (which on my system is owner by
root). I think that this does need to be fixed.
****
mythtv-common_0.20.2-0ubuntu10_all.deb
control/postinst contains the following:
NEW=$(mktemp -t mysql.txt-XXXXXX)
if [ -s /etc/mythtv/mysql.txt ]; then
INPUT=/etc/mythtv/mysql.txt
chown --reference="$INPUT" "$NEW"
chmod --reference="$INPUT" "$NEW"
else
INPUT=/usr/share/mythtv/mysql.txt.dist
chown mythtv:mythtv "$NEW"
chmod 660 "$NEW"
fi
($NEW later gets mv-ed into place).
This seems correct: it either inherits the ownership and mode of the file if it
already exists, or else it gets set to mythtv:mythtv and 660.
****
That's all I've been able to come up with. This was done by searching
for "mysql.txt" within the files contained in the deb archives (ar -x,
followed by tar zxvf of both data and control files, followed by fgrep
-r).
If you have other suggestions for diagnosing this I'd be delighted.
Thanks

Mode of /etc/mythtv/mysql.txt should be 660
