[lucid] Extra commas in user name field

[Tong Sun]

Tested version: ubuntu-10.04.1-desktop-amd64.iso

Condition: Having installed to HD using the "Install..." icon on the desktop, then boot into installed sys on HD.

Bug: I believe the following commas in user name field in /etc/passwd are extra.

$ grep ',,,:' /etc/passwd
avahi-autoipd:x:103:110:Avahi autoip daemon,,,:/var/lib/avahi-autoipd:/bin/false
avahi:x:104:111:Avahi mDNS daemon,,,:/var/run/avahi-daemon:/bin/false

This is perfectly normal, and not a bug.

Here's an example entry from WIkipedia:
jsmith:x:1001:1000:Joe Smith,Room 1007,[phone],[phone],email:/home/jsmith:/bin/sh
See the details like room number and phone number? Those are left blank for system users, resulting in the ",,,"s.
