Minor pep8 error in disklabel.py

0d413fc6 01/30/2014 01:53 pm Nikos Skalkotos

Fix a bug in disklabel enlarge code

If the disk size is greater that 8G then the CHS value of the MBR
will overflow. We should assign a fixed CHS value for this case.

922c1513 01/29/2014 06:04 pm Nikos Skalkotos

Remount every UFS partition rw just to be sure

In many cases although rw flags is passed to mount, the command
returns SUCCESS with a warning that the fs seems to be mounted ro.
Remounting rw does work.

4e364304 01/29/2014 05:00 pm Nikos Skalkotos

Use blockdev instead of partprobe after disklabel

partprobe creates the partitions by itself and since it does not
support disklabels, the disklabel partitons are not recreated

48af2403 01/29/2014 03:28 pm Nikos Skalkotos

Run partprobe after diskpart.py

After disklabel.py enlarges the partition the kernel must be
informed about this

Add support for resizing OpenBSD UFS file systems

de34e7aa 01/29/2014 12:14 pm Nikos Skalkotos

Add support for enlarging OpenBSD images

This only enlarges the partition and not the ufs file system

9787f9c2 11/05/2013 06:31 pm Nikos Skalkotos

Use /etc/motd to check if a system is OpenBSD

the rc scripts and kernel informations are added

Rename snf-passtohash.py to hashpwd.py

23f62254 11/05/2013 12:28 pm Nikos Skalkotos

accident because the grep pattern it used was more general than it
should be

666b80ee 11/04/2013 01:08 pm Nikos Skalkotos

The value of DO_SYNC property should be "yes"

In order to reenable fsync() the DO_SYNC image property should be
defined like this:
DO_SYNC=yes

f3bc7bef 11/01/2013 01:41 pm Nikos Skalkotos

Add a new PASSWORD_HASHING_METHOD image property

This can be used to override the hashing function ChangePassword
task uses. By default for linux and freebsd images, sha512 is used.
For OpenBSD blowfish and for NetBSD sha1.

63a3904a 11/01/2013 11:29 am Nikos Skalkotos

Fix a function name typo in AssignHostname task

b0e6727c 10/30/2013 06:21 pm Nikos Skalkotos

Add support for Blowfish passwd hashing algorithm

This is not supported by the Linux version of crypt and is needed
for NetBSD and OpenBSD. Add a new python-bcrypt packet in the helper
that implements the OpenBSD Blowfish password hashing algorithm.

b3c48174 10/30/2013 04:55 pm Nikos Skalkotos

Define {open,net}bsd_shadow vars in ChangePassword

does not work for now

3bb66fac 10/18/2013 11:03 am Nikos Skalkotos

helper: Fix a bug triggered by corrupted images

Fix a bug in get_partition_to_resize where the script would not stop
if the get_partition_table function failed, leading to bash syntax
errors.

2b79f174 04/22/2013 04:18 pm Nikos Skalkotos

Fix a bug in the extended partition detection code

Sometimes sfdisk --print-id does not return the id because it

overcome this.

e2510438 01/07/2013 08:09 pm Nikos Skalkotos

Mount all local filesystems when deploying images

we'll need to have it mounted to inject files on a user's home
directory.

0e707fe3 01/07/2013 04:07 pm Nikos Skalkotos

33e9b1b1 12/16/2012 09:41 am Nikos Skalkotos

Check for /etc/hostname in AssignHostname task

By default without investigating the distro of the guest VM, check

for static host names in systems that use the systemd startup deamon.

Magic SsysRq key

995a47c9 12/02/2012 11:14 am Nikos Skalkotos

Code cleanup

Make sure local variables are defined as local before they get assigned.
Having variables get defined and assigned in one line like this:

local var=foo

can sometimes cause problems. For example, this line:

local var=$(false)

will return 0 and the script will not fail if set -x is defined.

exist.

d309cd33 10/03/2012 04:56 pm Nikos Skalkotos

Suppress a reglookup warning

Hundred of warnings like this: `WARN: While quoting value for
'<registry_key>', warning returned: Data could not be interpreted,
quoting raw buffer.' are outputed when reglookup reads the registry
of a Windows 2012 system.

1ea8db72 09/29/2012 05:46 am Dimitris Aragiorgis

Xen support

Support launching helper domain on top of Xen hypervisor under PV mode.

Helper VM becomes hypervisor aware by passing hypervisor=$HYPERVISOR
in the kernel command line and thus acts accordingly (which logging
devices to use, what disk/floppy devices to expect, etc)...

beeb8f9f 09/28/2012 04:46 pm Nikos Skalkotos

c50358a6 09/06/2012 01:10 pm Nikos Skalkotos

Make sure EnforcePersonality runs last

When a users inject a file in an image that already exists,
we want to make sure that this file is not altered by any other task.
So, the EnforcePersonality task, is the last task that should run
before the image is unmounted.

  • Fix distro detection code to detect arch linux systems
  • Fix AssighHostname hook to successfully assign the host name on
    arch linux systems
