fish: New command 'sparse', like 'alloc' but to generate sparse files.
With sparse you can make sparse files, which is fun because you
can experiment with really large devices:
><fs> sparse /tmp/test.img 100G
><fs> run
><fs> sfdiskM /dev/vda ,
><fs> mkfs ext2 /dev/vda1 # very long pause here ...
><fs> mount /dev/vda1 /
To see the real (ie. allocated) size of the sparse file, use the du
command, eg:
><fs> !du -h /tmp/test.img
