Subject: Bump version number.
X-Git-Tag: bootcd-3.4-2~100
X-Git-Url: http://git.onelab.eu/?p=bootcd.git;a=commitdiff_plain;h=94c3d5266f7018911b048149763045deb60aad01

Bump version number.

Refactored old build_initrd() into init_initrd() and a new build_initd().
The new build_initrd() can be used to create both a big and small initrd.
