yes, as safe exit with TCONF and warning.

IMHO in any "non-safe" run.

I wanted tst_net_run() to behave similarly as tst_rhost_run(), which doesn't
warn about it. So I propose to add warning to both functions, but also add -q
flag (quiet), which suppress this warning.
The reason for quiet mode is, that (I suppose) there are cases when some
features is tested and TWARN isn't wanted. Some examples (looks -s is used often
in cleanup functions):
[ "$TST_IPV6" ] && mcast_cleanup6 || mcast_cleanup4
pkill -SIGHUP -f "$MCAST_LCMD"
pkill -9 -f "$MCAST_LCMD"
tst_rhost_run -c "pkill -SIGHUP -f '$MCAST_RCMD'"
tst_rhost_run -c "ip link delete ltp_v0 2>/dev/null"
if [ "$virt_tcp_syn" ]; then
sysctl -q net.ipv4.tcp_syn_retries=$virt_tcp_syn
nfs_setup_server() in testcases/network/nfs/nfs_stress/nfs_lib.sh:
if ! tst_rhost_run -c "test -d $remote_dir"; then
tst_rhost_run -s -c "mkdir -p $remote_dir; $export_cmd"
