Intro: what?

Resumo solves a requirement of the OSDL's Carrier Grade Linux 3.2 specification, which provides Linux with boot cycle detection and boot image fallback mechanism whenever serious error occurs. Serious errors are system stop errors such as kernel panic.

Resumo is grub patch which adds functionality of error handling. Whenever system can't start or finish correctly, boot loader selects safe(backuped) system image. Safe system images should be prepared in advance by backup tools. The backup tool is also available on this release.
