I need to re-construct the boot.img file used during the CD boot. I searched the forums for 'boot.img' and read all those. I read through http://www.knoppix.net/docs/index.ph...tomKernelHowto.
I am not running M$Win, I am not installing a new kernel or ISOLinux. I have the boot.img opened through a /dev/loop and have modified files. Unfortunately it looks like loop is read-only. So I copy these to a HD directory, make changes, and then what?

root@knop1:/bld/newstuff# ll bootimg/
total 1402
-rwxr--r-- 1 root root 107 Nov 19 15:28 boot.msg
-rwxr--r-- 1 root root 1791 Nov 19 15:28 f2
-rwxr--r-- 1 root root 256 Nov 19 15:28 german.kbd
-r-xr--r-- 1 root root 7836 Nov 19 15:28 ldlinux.sys
-rw-r--r-- 1 root root 9258 Jan 8 08:29 logo.16
-rwxr--r-- 1 root root 489495 Nov 19 15:28 miniroot.gz
-rwxr--r-- 1 root root 2797 Jan 8 08:27 syslinux.cfg
-rwxr--r-- 1 root root 921593 Nov 19 15:28 vmlinuz

Note modified files. Now what is the 'mkisofs' command to rebuild the boot.img file? Then I will put it back into the remastering structure.

Thanks in advance
