Ehm, why do we get ourselves in trouble like this? We have an amount of static uid/gid combinations. UIDs below 1000 have been reserved for system things for a long while, GIDs below 100 have been reserved for system things also. We've been using static UID/GIDs in packages for now. This has always brought up weird issues with people that have other users using these UID/GID combinations. When I take a look at the Debian boxes I maintain, I see these groups: crontab:x:101: ssh:x:102: ntp:x:103: ssl-cert:x:104: postfix:x:105: postdrop:x:106: When I look on a different debian box, I see these numbers are in a different order, or different users assigned to these GIDs. I think it's better to change packages like policykit instead to add groups and change ownership and permission in post_install and post_upgrade.
