$Self <options>
This is a wrapper for two scripts:
adapt-ks-template adapts a kickstart template
create-boot-floppy creates a bootable floppy image
Because the ipxe config and the kickstart config need many of the same options,
it's simpler to call a wrapper with *all* options, and have it call the
individual scripts.
The results of both scripts will be moved to a directory, which is (assumed to
be) published by a webservice, thus making them available for download.
The combination of boot-floppy and kickstart config will be able to bootstrap
a (CentOS 7) instance up to, and possibly including, cosmos+puppet bootstrap
Options:
-D, --domain domain, to complete FQDN
-G, --gateway Gateway of target system
-H, --host hostname of the target system
-I, --ip IP address of target system
-K, --kserver Kickstart server
-M, --netmask Netmask of target system
-N, --nameserver Nameserver of target system
-P, --publish-path Path where results will be stored
-S, --cosmos-hash Hash used by cosmos to verify stuff
--boot-dev device to install bootloader on
--root-dev device to use for system
--cosmos-tag Tag in ndn-sysconf to reference
--template Template to use. This is a relative path, plus the
name of the template file. Example:
supermicro/SYS-5018D-FN8T/dtn-10g.ks
dell/R7425/100g-dtn.ks
--inst-cmdline add stuff to the install system kernel command line
--krnl-cmdline add stuff to the destination system kernel command line
--sec-ip IP of secondary interface
--sec-nm Netmask of secondary interface
--sec-gw Gateway of secondary interface
-h, --help this
If --cosmos-hash is set to 'disabled', the kickstart stage should skip cosmos
bootstrapping, and leave the system unmanaged.
If -N, -K, -S options are not given, default values are provided.
To avoid shell interpretation of whitespace in --inst-cmdline and
--krnl-cmdline use escaped semicolon:
To achieve this:
console=tty1 console=ttyS0,115200n8
write this:
console=tty1\;console=ttyS0,115200n8
