Options:
-b Boot Params Additional boot parameters passed to grml2usb
- -c Directory Copy files from directory to generated iso
+ -c Directory Copy files from directory to generated ISO
-f Force overwrite of existing target.iso
-r BootParam Remove specified boot params.
Could be specfied multiple times.
-p <grml2usb param> Add the specified parameter to the grml2usb
commandline. For a list of valid parameters have
a look at the grml2usb manpage.
- Could be specfied multiple times.
- -s URI Generate a small iso file which downloads the squashfs
+ Can be specified multiple times.
+ -s URI Generate a small ISO file which downloads the squashfs
file from the specified URI. Please note that due to
restrictions in the bootprocess only IPs are allowed.
Supported protocols are: http and ftp
$0 -s http://192.168.23.42:8000/grml/ -o small.iso grml64_2010.12.iso
Will generate a file small.iso which tries to download the squashfs file from

- directory as the iso file.
+ http://192.168.23.42:8000/grml/ - the squashfs file is placed in the same
