[Compass-ci] Re: [PATCH lkp-tests] iso2rootfs: fix domain name cannot be resolved problem

{ echo "${config_rootfs}" | grep -qw 'dns' || return 0

• grep "^dns=none" $config_file || sed -i '/^[main]/adns=none' "${ROOTFS_DES_DIR}/etc/NetworkManager/NetworkManager.conf"

keep silence for grep, and too long line.

=> grep -s "^dns=none" $config_file || { sed -i '/^[main]/adns=none' "${ROOTFS_DES_DIR}/etc/NetworkManager/NetworkManager.conf" }

Thanks Luan Shengde
