Hi, the FAI packages would be affected by an isc-dhcp removal as follows:
- for fai-quickstart the dependency can easily be removed - For almost all FAI environments we need to create the nfsroot which uses the network-legacy module of dracut, that needs dhclient. Without a nfsroot most things will not work. - The default FAI installation environment is a network installation which uses the network-legacy module, that needs dhclient. dracut supports other network modules for e.g. systemd-networkd, but currently FAI is sticked to network-legacy. - The FAI installation additional calls dhclient using the option -sf for calling a FAI specific script file to receive optional settings without setting the network. Not sure if other dhcp clients support this and if the FAI specific script will still work. - FAI provides a ready-to-go config script for a FAI server (inlcuding a sample ISC dhcpd.conf) that sets up the ISC DHCP server. This example would not work any more.
