NAME

uck-remaster-unpack-rootfs - Ubuntu Customization Kit rootfs unpacking script

SYNOPSIS

uck-remaster-unpack-rootfs [-m] [remaster-dir]

DESCRIPTION

uck-remaster-unpack-rootfs extracts the root file system stored in compressed form from an unpacked ISO image (cf. uck-remaster-unpack-iso). If the argument is not specified, it defaults to ~/tmp.

By default uck-remaster-unpack-rootfs works by mounting the rootfs image on a temporary directory and then copying all contents to the directory remaster-root under remaster-dir.

If the -m option is specified, a set of loop back and unionfs mounts will be used to create a writeable instance of the rootfs image accessible as remaster-root under remaster-dir. The modified parts of the root file system will be cached in remaster-root-cache under remaster-dir. This is a lot faster and requires less disk space, but may not work for all scenarios and mandates the installation of some additional software (i.e. fuse-utils and unionfs-fuse).
