Couldnt believed when i saw this go from 7.2-7.4.2 but the long wait for creation of knopix-data.img led me to this.
first the comment from /init:
# I thought that creating a sparse file would be quicker than writing
# all data completely, but unfortunately, it has bad side effects if
# the underlying FAT file system is fragmented. -KK
# dd if="$src" of="$1" bs=1M seek="$(($2 - 1))" count=1
No, Klause the fast way works with a ext2+ fs but it's the bug below that led you to believe it doesn't!
Please correct me if I am wrong.Check the fix script below that changes 1 byte (what major work you save):
The bug is described in the details of the fix script (all to fix one byte in the init script!!!!):
#!/bin/bash
# Rev: $Id: fixminirt.sh 618 2015-04-13 23:49:24Z knoppix $
# Author: koolb@hotmail.com
# Description: Fix minirt.gz to e2fsck knoppix-data.img from Knoppix7.2-4
# for USB style installations on HD (or USB of course).
# Usage: # optionally, specify addtional boot areas besides /mnt-system/boot,
# eg /dev/sda2/boot
# fixminitrt.sh [/path/to/additional/boot] # where {iso,sys}linux* dirs are
#
# Details:
# This handles an issue Knoppix 7.2-4 for those booting off USB or have
# multiple usb style boots to HD or otherwise.
# This is bug in the minitrt/init script's checkfs() function
# in Knoppix7.2-7.4.2. checkfs() which igores the file passed.
# # checkfs partition filesystem
# checkfs(){
# local p="$1" ... # we assign to $p
# ...
# ... e2fsck -y "$h" ... # bug: uses $h instead of $p: fix $h -> $p
# ...
# }
# This will find all minirt.gz files and update the init script in each.
# . ~/scripts/functions - used for debugging shell scripts
