Package: dar
Version: 2.3.5-1
Severity: normal
dar doesnt support sparse files and manpage says nothing about that, so you
need to do some experimentation to see if dar supports it or not. It will be
good to add sparse files support, but until that, please add a note in the
manpage saying that we don't have it at the moment. This is probably
unnoticeable when you use the compression flag (-z), because big chunks of
zeroes are easily compressed, but if you dont use it, then the resulting
archive will be big / not sparse. Check this:
serge:/tmp# mkdir -p test/files
serge:/tmp# cd test/files
serge:/tmp/test/files# dd of=sparse-file bs=1024 count=0 seek=10240
