Automatically mount VDI, zeroing every EXT partitions and compact the VDI file.
I recommand to put this into "~/.local/bin" to call it from everywhere.
Dependencies (and packages in Ubuntu):
- qemu-nbd (provided by "qemu-utils")
- zerofree (provided by "zerofree")
- vbox-manage (provided by "virtualbox")
To fully exploit this tool:
- Avoid logical partitions
- Do not encrypt your partitions
- Avoid having multiple large partitions
- Prefer multiples VDI files for large partitions
- Format your large partition in EXT4
- Place your large partition at the end
- Fill all available space with your large partition
Right examples:
[ EFI ][ ------ ROOT ------ ].vdi[ EFI ][ ------ ROOT ------ ].vdi +[ --- HOME --- ].vdi[ EFI ][ BOOT ][ ------ ROOT ------ ].vdi------ EXT4 (without partition table) ------.vdi
Wrong examples:
[ EFI ][ ------ ROOT ------ ][ --- FREE SPACE --- ].vdi[ EFI ][ BOOT ][ ------ LUKS ROOT ------ ].vdi[ EFI ][ BOOT ][ ------ LOGICAL ROOT ------ ].vdi[ EFI ][ ------ ROOT ------ ][ --- HOME --- ].vdi[ EFI ][ ------ ROOT ------ ][ BOOT ].vdi[ EFI ][ ------ WINDOWS 10 (NTFS) ------ ].vdi
