[Bug 1091788] Re: debian-installer: creation of volume group (LVM) fails if hostname corresponds with an existing device name

[Dmitrijs Ledkovs]

** Description changed:

- Imported from Debian bug http://bugs.debian.org/565947:
+ [Impact]
  
- Package: debian-installer
- Version: 20091215
- Severity: normal
+  * Auto LVM recipe fails to install, if hostname matches one of existing
+ volume group names or devices under /dev/
  
+ [Test Case]
  
- Using the guided partition mode with LVM setup might fail if the
- chosen hostname corresponds with an existing device name.
+  * Do not preseed default VG name & specify a hostname as clashing with
+ a device under /dev/, e.g. "port". Before the installation fails, now
+ "port-vg" VG name is used.
  
- Example:
+  * Specify a clashing default VG name, e.g. port. Before the
+ installation fails, now a message appears that "This name is in use
+ already" and asks to select a different one.
  
- The hostname is set to "vcs". The name of the automatically created
- volume group is "vcs" as well then, though creation and use of it
- fail because /dev/vcs is an existing character device already.
+ [Regression Potential]
  
- The *source* of the error isn't visible in the user interface but
- just in the syslog.
- 
- regards,
- -mika-
+  * Some systems may expect default VG group name to match the hostname
+ exactly. In those cases "partman-auto-lvm/new_vg_name" should be
+ preseeded explicitly to an expected value.
