Hi.I'm investigating using --sparse in GNU cpio (2.4.2 from RedHat 7.1) and GNU tar (1.13.19 from RedHat 7.1) as part of my assignment for acheiving a GIAC Certified Forensic Analyst certification from the SANS Institute.
My analysis is that --sparse is fairly useless in GNU tar, and mostly works in GNU cpio, but that holes at the end of a file don't get created (I'm guessing the appropriate lseek is done, but no final write is ever done).
I see that GNU cpio 2.5 was *just* released. Do you know if happens to address this problem? I don't see anything in the change log, but there is an entry that lots of changes were taken from the various Linux distributions.
Yes, I know I should get the code and try it out, but I thought I'd ask first. Beside, if you don't know about this... now you do.
Thanks greatly. -- Chris Calabrese, GCIA Internet Security Analyst MerckMedco.com
