Before this patch sysrescue-configuration.lua was executed twice each boot: (1) during initramfs stage (2) in the regular system as sysrescue-configuration.service While in theory both runs should create the same output, this isn't guaranteed and differences could appear for example because of network issues. Finding and debugging these is difficult because the output of sysrescue-configuration.lua created during initramfs isn't available anymore when the final system is running. This patch lets sysrescue-configuration.lua just run once during initramfs. The output JSON file is then written to the new tmpfs mounted dir /run/archiso/config/. This dir is also made the new default location for sysrescue-effective-config.json. A symlink from /etc/sysrescue/sysrescue-effective-config.json to the new location is created for compatibility with previous releases.
