[PATCH RFC] sysprep: remove user accounts
by Wanlong Gao
Hi Rich,
This patch attends to remove the user accounts in the guest,
I send this out to request your comments, if the concept
is correct and you can point out some syntax error for me.
Thanks a lot,
Wanlong Gao
Remove user accounts except the root user.

Cannot login after modification shadow file with guestmount
by Daneel Yaitskov
Hi.
I have a VM with CentOs6.2 on KVM. I mount an image of the VM when it's
not working with guestmount:
root@diehard:~# guestmount -a named-centos.img -i tmp
vi /etc/shadow
insert comment line into the file (esc yy p 0 i # esc :wq!), save changes,
unmount the image, turn on the VM, and I cannot login.
I cannot login even if I recover the shadow file.
root@diehard:~# guestmount --version
guestmount 1.16.15

Notes on libguestfs with Ubuntu 12.04 (Precise)
by Richard W.M. Jones
Ubuntu are now supplying a libguestfs package (or to be more accurate,
they are just copying the Debian package) but it doesn't work out of the box.
There is a bug in apt which we worked around in febootstrap 3.14, but
the supplied version of febootstap is only 3.12. Hence you will get
errors like this during installation:
febootstrap: aptitude: error: no file was downloaded corresponding to package <some package name>
and you'll get the same error if you try to build from source.
The solution is to build febootstrap 3.14:
cd /tmp
sudo apt-get build-dep febootstrap
sudo apt-get install devscripts
apt-get source febootstrap
wget http://people.redhat.com/~rjones/febootstrap/files/febootstrap-3.14.tar.gz
tar zxf febootstrap-3.14.tar.gz
cd febootstrap-3.14
rm -rf debian
cp -a ../febootstrap-3.12/debian .
vi debian/changelog
# change the first line: 3.12 -> 3.14
debuild -i -uc -us -b
That will create an febootstrap 3.14 .deb file in /tmp which you can
install:
sudo dpkg -i ../febootstrap_3.14-1_amd64.deb
Then you can go ahead and use the libguestfs package:
sudo update-guestfs-appliance
or compile libguestfs from source.
There is another problem which you may hit, if you add a completely
blank disk to libguestfs (this also affects libguestfs-test-tool):
