Bug#287931: [patch] Checking partition table type using parted_server

[Jurij Smakov]

Package: partman
Severity: wishlist
Hi,
Attached is the partman patch (against current svn source) which 
implements the GET_DISK_TYPE command in parted_server.c. It makes it 
possible to get the partition table type of the disk (essentially, it just 
returns disk->type->name) by doing something like

open_dialog GET_DISK_TYPE
read_line disk_type
close_dialog
This is useful for various arch-specific hooks (at least on sparc and 
alpha) which check that the disk where kernel is installed has a partition 
table type supported by the loader.
