Comment 24 for bug 1452202

Additional note about the re-work.

The original patch I have submitted works as expected by overriding the hostname but ...

I noticed after more testing that if LVM is used partman rely on "/etc/hostname" to name the VG[1] for instance : <hostname>--vg-root.

Unfortunately, the current patch does the hostname overriden after that the Volume Group is created which make the vg name and hostname inconsistent.

The re-work of the patch will consist on making sure the hostname override happens before the vgcreate to keep things consistent and not having a vg group that display the hostname before it has been overriden.

[1] - lib/auto-lvm.sh
278 auto_lvm_perform() {
279 # Use hostname as default vg name (if available)
280 local defvgname pv vg_file vg_name
281 # $pv_devices will be overridden with content from $VG_MAP_DIR
282 local pv_devices
