# EL riscv64 media and diskless images: the installer kernel/initrd live under
# images/pxeboot like x86 and aarch64 media, and riscv64 diskless images need
# their own default network drivers and lib64 resolver libraries. The
# behavior is pinned without running the database-backed plugins: the arch
# conditions are asserted in the shipped source and the resolver block is
# extracted and evaluated directly.
