[PATCH] sysprep: handle distro specific sysv scripts
by Olaf Hering
Currently firstboot would only work on redhat-based images.
Handle redhat-based, suse-based and debian guests, error out in case of an
unknown distro.
Update firstboot.sh:
- make sure scripts exists and can be executed
- add LSB header to avoid insserv warnings later on
- run script only if called with "start"
Update functions, pass only required options.

simplify debugging of guestfsd
by Olaf Hering
Sometimes guestfsd fails to gather info, and the virt-<tool> -v output
is usually not useful to figure out whats going on within the temporary
guest. I see the /init script has support to run guestfsd with a debug
tool, which is currently valgrind.
Granted, valgrind support is a compile time thing. What would be a good
way to optionally run guestfsd with strace or gdb?
Should each tool get a new option, something like 'virt-<tool>
--debug=strace', or should it be like 'XYZ_STRACE=1 virt-<tool>'?

Fwd: hivex: patch for read support of "li"-records from "ri" intermediate
by Richard W.M. Jones
[The bug which this fixes is:
https://bugzilla.redhat.com/show_bug.cgi?id=717583 ]
----- Forwarded message from Peter Fokker <peter(a)berestijn.nl> -----

Subject: hivex: patch for read support of "li"-records from "ri"
intermediate
User-Agent: SquirrelMail/1.4.9a
Richard,
Thank you for creating the hivex-library. Studying your source code helped
me a great deal to better understand the internals of the Windows Registry.
However, while I was browsing a real-world SOFTWARE-hive (XP, SP3) I
could not browse to the '\Classes' key. Instead I got this (debug)-message:
get_children: returning ENOTSUP because ri-record offset does not
point to lf/lh (0x49020)
I tracked this issue down and I discovered that the intermediate
"ri"-record may not only contain offsets to "lf" and "lh" but to
"li"-records too.
Attached is a patch against hivex.c v1.3.3 that recognises
"li"-records referenced from "ri"-records. For me this fixed the issue
with browsing the '\Classes' key.
Note that I have not fixed the related problem of rewriting
"li"-records when inserting a new subkey or deleting an
existing one. This sure would cause problems when I were to
add/delete a subkey to/from '\Classes'.
I would very much appreciate it if would be so kind to take a look at
my patch, allthough I cannot blame you if you immediately dump this
unsollicited message+patch from some random stranger from The Netherlands.
Kind regards,
--Peter Fokker

no man page for guestfsd
by Olaf Hering
rpmlint complains that guestfsd has no man page. I think its a good
idea to provide one also for guestfsd.

[PATCH v2] inspection: Fix calls to case_sensitive_path (RHBZ#858126).
by Richard W.M. Jones
From: "Richard W.M. Jones" <rjones(a)redhat.com>
Don't assume that if guestfs_case_sensitive_path returns NULL, that it
means the file does not exist.
The (previously undefined) behaviour of case_sensitive_path was that a
NULL return meant "either the file doesn't exist or some other error".
However in commit 973581780d8a006f336684fef6762801402d775d this was
changed so that if the last element of the path didn't exist, it was
assumed to be a new file and the (non-NULL) path of the new file is
returned.
This change breaks code (including in libguestfs) which tries to use
case_sensitive_path as a dual-purpose call to fix-up a path for
Windows and test if the file exists. Such code should be rewritten so
that it explicitly tests for file existence after calling
case_sensitive_path.
I examined all the calls to case_sensitive_path in libguestfs and
modified them where necessary.

guestfish hang when exec command.
by xuanmao_001
Hi,
I have some issues with libguestfs. I download the libguestfs-0.18.3 source code and read the README file.
it requested qemu >= 0.13, my qemu version is qemu-1.0.1
requested kernel version >= 2.6.34, my kernel version is 3.1.4
the most of requirement for compiling I reached. but I completed compiltion and executed command.
the guestfish hang there.
the following was my operating steps:
tar -Jxvf appliance-<VERSION>.tar.xz
Then copy all four files:
* kernel
* initrd
* root
* README.fixed
into a directory somewhere, eg. /usr/local/lib/guestfs/appliance/
Then build libguestfs (>= 1.16.7 or >= 1.17.10) from source, disabling
the normal appliance and daemon:
./configure --disable-appliance --disable-daemon
make
make install
Set LIBGUESTFS_PATH to the path where you unpacked these files, eg:
export LIBGUESTFS_PATH=/usr/local/lib/guestfs/appliance/
then executed command:
virt-copy-out -d GuestName 'win:c:\windows\system32\config' .
the command hang here.
Is there something going wrong? give me some help, thanks!
