By the way, below is a small change which appears to fix the link issue I

Well, yes, that will fix the link issue, but it will also make fs-utils not work entirely correctly on Linux (observe the output of fsu_ls -l, for example).

Thanks! fs-utils seems exactly what I was looking for...
I got some link error (like below) when compiling fs_utils, but the
Makefile gave me enough information to write a small example which seems
working.

/home/lsun/workspace/gitrepo/rump/rumpctrl/rumpdyn/lib/librumpkern_sys_linux.so:
undefined reference to `rumpns_compat_50_sys_settimeofday'

I know how to fix it, but I need to batch the fix with some other changes, so it'll take a few more hours.

p.s. please don't top-post on the mailing list. as you can see from my response being "upside-down", it makes responding to specific parts of mails very inconvenient.
