Re: [Clonezilla-live] Clonezilla / Partclone ext4 problem

[Andreas W. <and...@nt...>]

Hi,

omitting the -C option does not work when restoring to a file (as
expected). I also created SHA1 checksums in order to verify the image is OK.

Mounting the partition from an image created with dd works, so it seems
this is really a bug in clonezilla or partclone.

Regards,
Andreas
