On SuSE there is a config process run out of cron
 that sets permissions and ownerships according to templates.

The base set are in	/etc/permissions

Then overlay your choice of poison:

Then your custom files	/etc/permissions.local

The point is that running this as part of the version commit
 sets all the ownerships and permissions according to a file.
And the file is under version control.

Here's a bit of /etc/permissions.secure:

# /etc
/etc/crontab      root:root          600
/etc/exports      root:root          644
/etc/fstab          root:root          644
/etc/ftpaccess    root:root          644
/etc/ftpusers      root:root          644
/etc/inetd.conf    root:root          644
/etc/inittab        root:root          644
/etc/mtab         root:root          644

/var/lib/nfs/rmtab   root:root          644
/etc/syslog.conf      root:root          600

# suid system programs that need the suid bit to work:
