[PATCH] Add a test for an executable stack in libguestfs.so
by Matthew Booth
I've updated the patch. It's now in regressions, and checks both libguestfs.so
and the guest daemon. It occurs to me that it's the daemon that's would get an
executable stack from the specific patch I posted the other day. However, would
this actually matter specifically for the daemon?

[PATCH] build: generate some just-removed files in po/
by Jim Meyering
My change that removed most of po/*
should have included this patch to generate two required files.
Without this change, "make -C po" fails like this:
make: Entering directory `/o/libguestfs/po'
make: *** No rule to make target `/config.status', needed by `Makefile'. Stop.
...
Once you've pulled this change, you will need to
run ./bootstrap manually to make it take effect.

syntax-check changes
by Jim Meyering
With this, "make syntax-check" runs a few more tests, all passing.

[PATCH] Fix swapon_label test
by Matthew Booth
The swapon label test has a side-effect, in that it creates a new partition.
This causes the later failure of the list_partitions test.
This change causes the swapon_label test to scrub /dev/sdb after the test, and
then re-read the partition table.

Re: [Libguestfs] How to get information about the guest filesystems by libguestfs
by Charles Duffy
I looked into it -- what exists in newer versions (via "guestfish -i") isn't
really built-in as such, but rather calls virt-inspector. There is no C
implementation presently, and you would need to rewrite the (fairly complex)
Perl code in C to get that functionality independent of it.
That's certainly a feasible thing to do -- but why is it so important to you
that everything be pure C?
