percona units syncronize several @ localhost accounts from mysql/0 leaving invalid debian-sys-maint creds

[JuanJo Ciarlante]

As per summary, finding at mysql/1 creds from mysql/0 host accounts,
this query gives verbatim *same* result both at mysql/0 and mysql/1:

mysql> select user, host, password from mysql.user where host = 'localhost' ;
+------------------+-----------+-------------------------------------------+
| user | host | password |
+------------------+-----------+-------------------------------------------+
| debian-sys-maint | localhost | *9ACBDF3D4XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX |
| root | localhost | *F2C1A0F53XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX |
| sstuser | localhost | *077E9517AXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX |
+------------------+-----------+-------------------------------------------+

while their respective content at e.g. /etc/mysql/debian.cnf differ.

The only account which will not be sync'ed with on disk configuration is the debian-sys-maint account; this is tricky as this is maintained by the packaging for binary upgrade purposes.
