Use wipefs to clear old signatures before creating new file systems (#688882) Previously the function erase_filesystem_signatures() was used to clear file system signatures when a new partition was created and when an existing partition was formatted with a file system. However this was only available with libparted <= 2.4 and then only for the file systems which libparted supports. Having multiple different file system signatures on a partition leads to misidentification of file system. For example creating a nilfs2 over the top of a fat32 file system is detected as a fat32, not nilfs2. This shows that old file system signatures must be cleared before a new file system is created. Fix by always using "wipefs -a /dev/PARTITION" command to clear all old file system signatures rather than libparted API calls. Failure from wipefs is only considered a warning so doesn't fail the file system creation. (This doesn't yet fully meet the "MUST be cleared" requirement above. Will be fully met later in this patchset). Output from the wipefs command is displayed as a new sub-step which looks like this: v Format /dev/sda7 as xfs 00:00:05 > calibrate /dev/sda14 00:00:01 v clear old file system signatures in /dev/sda7 00:00:01 [NEW] > wipefs -a /dev/sda7 [NEW] > set partition type on /dev/sda7 00:00:02 v create new xfs file system 00:00:01 > mkfs.xfs -f -L "" /dev/sda7 Also signatures are only cleared immediately before a new file system is written and not when an unformatted partition is created. This allows recovery from accidental partition deletion by re-creating the deleted partition as unformatted. Bug #688882 - Improve clearing of file system signatures
