Not sure I understand that one...<br>

<br>
I still think it should be made to be target-finalize hooks, one for<br>
each option.<br>
<br>
Also, I don;t get why you want to use the one in factory, rather than<br>
tweak the existing /etc/nsswitch.conf that has already been installed,<br>
like the other nss plugins do.<br>
<br>
And then, at the end. copy the one from /etc/nsswitch.conf over to the<br>
one in factory. That last one is a bit more tricky to come up with<br>
correctly, as this must be done after all nss plugins have had a chance<br>
to tweak nsswitch.conf. So I guess we should extend SYSTEMD_ROOTFS_PRE_CMD_HOOKS<br>
with a new hook that copies /etc/nsswitch.conf over to the factory.<br>
