Hi, As SystemImager developer I’m heavily using dracut to generate the imager. (SystemImager is a software aimed at cluster nodes images deployment) I’ve just discovered that in CentOS-8.1, the 40network dracut module is now splitted in 35network-legacy and 35network-manager. My systemimager dracut module used to requires network, and did use net-lib.sh to retrieve some network informations. It did also use /tmp/net.ifaces that is also used by net-lib.sh. It was also heavily using /tmp/dhclient.$DEVICE.dhcpopts or /tmp/net.$DEVICE.override /tmp/leaseinfo.$DEVICE.dhcp.ipv4 in a initqueue/online hook ($DEVICE is $1 in this hook) Now that 40network uses by default 35network-manager, all is broken: • Net-lib.sh (from 40network) that uses /tmp/net.ifaces is broken. (e.g. configured_ifaces() returns nothing). • /tmp/dhclient.$DEVICE.dhcpopts or /tmp/net.$DEVICE.override don’t exists anymore My question is thus simple: • Will you fix net-lib.sh? (or will it move to 35network-legacy?) • How do I retrieve DHCP specific custom fields like $new_option_144 that was present in /tmp/dhclient.*.dhcpopts? o Note: on SuSE, I was using /tmp/leaseinfo.$DEVICE.dhcp.ipv4) o Ideally, is there an equivalent of /etc/*dhcpopts or /etc/*override that could be sourced and that would define device relevant informations? Note:s • need to keep compatibility with CentOS-6, CentOS-7, SuSE, … • I’d like to avoid 35network-legacy as it won’t last forever and after imaging, I give control back to system and finish to boot the just installed OS without rebooting. Using legacy-network would prevent doing direct boot. • At minimum, I need to get needed infos for creating the ifcfg file. I also need to know the dhcp server ip (if using dhcp) and getting options would let mee keep compatibility with old systemimager. Any help would be greatly appreciated as for now I don’t see a clean way to handle the change. (nmcli doesn’t work as it doesn’t run as a daemon when initqueue/online hook is triggered) SystemImager dracut module can be found here: https://github.com/finley/SystemImager/tree/SystemImager-NG/lib/dracut/modules.d/51systemimager Best regards, Olivier. PS: I've found this https://bugzilla.redhat.com/show_bug.cgi?id=1727904 and I'm afraid to be stuck :-/ -- Olivier LAHAYE
