oops.  you can surely remove /srv/dns though.
what's the difference between boot and dns...?

I got it: #s is doing a special treatment for boot in
/sys/src/9/port/devsrv.c:/^srvremove .
	if(strcmp(sp->name, "boot") == 0)
		error(Eperm);

I'd rather have #s only removable by hostowner/file owner instead.
Would this change break something?
