Emerge with "--root" doesn't create users in target directory that exists in builder's system
Steps to Reproduce:
1.Be sure that /etc/passwd doesn't have "quagga" user
2.Create /target-system directory
3.Perform "emerge --root=/target-system quagga"
4.Look at /target-system/etc/passwd
There is no "quagga" line in /target-system/etc/passwd
Adding "quagga" user (in that case) into /target-system/etc/passwd
Assuming you tried =net-misc/quagga-0.99.22.4, this work would be done in the enewuser and enewgroup calls in pkg_setup().
