Change default DHCP timeout to 60 seconds instead of 30 to avoid issues with STP (Spanning Tree Protocol). STP defaults to 15 + 15 seconds on a lot of popular devices for listening and learning states. Which if not disabled (which you should on access switches, sure..) most netboots will fail intermittently due to the port access on switches performing port learning while the machine is trying to get DHCP leases. - mkinitcpio-archiso32 - Archlinux32 initcpio scripts used by archiso

Change default DHCP timeout to 60 seconds instead of 30 to avoid issues with STP (Spanning Tree Protocol). STP defaults to 15 + 15 seconds on a lot of popular devices for listening and learning states. Which if not disabled (which you should on access switches, sure..) most netboots will fail intermittently due to the port access on switches performing port learning while the machine is trying to get DHCP leases.

Added comment referencing to why the 60 seconds. More information can be found here: https://www.ciscopress.com/articles/article.asp?p=2832407&seqNum=6 and https://techhub.hpe.com/eginfolib/networking/docs/switches/5980/5200-3921_l2-lan_cg/content/499036677.htm
