Subject: Can coreutils stat dismounted filesystem?

Hi
In fact, It is not a bug.
I write to this email address according the link:
http://www.gnu.org/software/coreutils/faq/coreutils-faq.html#How-do-I-add-a-question-to-the-FAQ_003f.

I need filesystem details (size, type, freespace, etc). The most
appropriate utility for this purpose is coreutils 'stat' (as I could
find).
In my case, filesystem to be probed can be both mounted and dismounted.
In case of mounted filesystem I have no questions.
In case of dismounted filesystem I cannot get her details, because I
cannot specify any file in it.

So, this is a question: Can coreutils 'stat' utility display details
of dismounted filesystem? Or may be another coreutils utility can?

Thanks,
v99glu.

Thanks for telling us where you spotted the bug-coreutils@ reference
That is no longer the correct address, and I've just fixed that page
and added some clarification.  FAQ-related discussion is better
directed to the coreutils <at> gnu.org list.

Your message to the bug- list has automatically opened a bug "ticket"
http://debbugs.gnu.org/8823
which means someone has to manually close it.
(I'm doing that via this message with the Cc to 8823-done@...)

If a file system is not mounted, then no coreutils program can do what
you want.  However, if you really need to inspect a file system without
mounting it, consider libguestfs (http://libguestfs.org/).
