From: Pu Lehui <pulehui@xxxxxxxxxx> Support vmtest to use local rootfs image generated by [0] that is consistent with BPF CI. Now we can specify the local rootfs image through the `-l` parameter like as follows: vmtest.sh -l ./libbpf-vmtest-rootfs-2024.08.22-noble-amd64.tar.zst -- ./test_progs Meanwhile, some descriptions have been flushed.
