Options:
- -b Boot Params Additional boot parameters passed to grml2usb
- -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.
+ -b Boot Params Additional boot parameters passed to grml2usb
+ -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.
+ 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
+
+ Examples:
+ $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
+ http://192.168.23.42:8000/grml/ - the squashfs file is placed in the same
+ output directory as the ISO file.
