"${0} <option>", where <option> is one or more of:
$(echo -e "\e[97m --help, -h\e[0m")
What you're looking at.
$(echo -e "\e[97m --autobuild=*, -a=*\e[0m")
Headless mode. Skip the dialog wrapper, provider note screen and interactive kernel
selector dialog. Change '*' to your desired Linux kernel and trim the
'linux-image-' string to select a specific kernel, e.g. '--autobuild=6.12.30+bpo-amd64'.
$(echo -e "\e[97m --architecture <STRING> one of <amd64 | arm64>\e[0m")
A string reflecting the architecture of the Live System.
MUST be provided.
$(echo -e "\e[97m --build-directory </path/to/build_directory>\e[0m")
Where the Debian Live Build Image should be generated.
MUST be provided.
$(echo -e "\e[97m --change-splash <STRING> one of <club | hexagon>\e[0m")
A string reflecting the GRub Boot Screen Splash you want to use.
If omitted defaults to "./.archive/background/club.png".
$(echo -e "\e[97m --cdi (Experimental Feature)\e[0m")
This option generates a boot menu entry to start the forthcoming
'CISS.debian.installer', which will be executed after
the system has successfully booted up.
$(echo -e "\e[97m --contact, -c\e[0m")
Displays contact information of the author.
$(echo -e "\e[97m --control <INTEGER>\e[0m")
An integer that reflects the version of your Live ISO Image.
MUST be provided.
$(echo -e "\e[97m --debug\e[0m")
Enables debug logging for the main program routine. Detailed logging
information are written to "/tmp/ciss_live_builder_$$.log"
$(echo -e "\e[97m --dhcp-centurion\e[0m")
If a DHCP lease is provided, the provider's nameserver will be overridden,
and only the hardened, privacy-focused Centurion DNS servers will be used:
- https://dns01.eddns.eu/
- https://dns02.eddns.de/
- https://dns03.eddns.eu/
$(echo -e "\e[97m --jump-host <IP | IP | ... >\e[0m")
Provide up to 10 IPs for /etc/host.allow whitelisting of SSH access.
Could be either IPv4 and / or IPv6 addresses and / or CCDIR notation.
If provided, than it MUST be a <SPACE> separated list.
IPv6 addresses MUST be encapsulated with [], e.g., [1234::abcd]/64.
$(echo -e "\e[97m --log-statistics-only\e[0m")
Provides statistic only after successful building a
CISS.debian.live-ISO. While enabling "--log-statistics-only"
the argument "--build-directory" MUST be provided while
all further options MUST be omitted.
$(echo -e "\e[97m --provider-netcup-ipv6\e[0m")
Activates IPv6 support for Netcup Root Server. One unique
IPv6 address MUST be provided in this case and MUST be encapsulated
with [], e.g., [1234::abcd].
$(echo -e "\e[97m --renice-priority <PRIORITY>\e[0m")
Reset the nice priority value of the script and all its children
to the desired <PRIORITY>. MUST be an integer (between "-19" and 19).
Negative (higher) values MUST be enclosed in double quotes '"'.
$(echo -e "\e[97m --reionice-priority <CLASS> <PRIORITY>\e[0m")
Reset the ionice priority value of the script and all its children
to the desired <CLASS>. MUST be an integer:
1: realtime
2: best-effort
3: idle
Defaults to '2'.
Whereas <PRIORITY> MUST be an integer as well between:
0: highest priority and
7: lowest priority.
Defaults to '4'.
A real-time I/O process can significantly slow down other processes
or even cause them to starve if it continuously requests I/O.
$(echo -e "\e[97m --root-password-file </path/to/password.txt>\e[0m")
Password file for 'root', if given, MUST be a string of 20 to 64 characters,
and MUST NOT contain the special character '"'.
If the argument is omitted, no further login authentication is required for
the local console. The root password is hashed with an 16 Byte '/dev/random'
generated SALT and SHA512 Hashing function and 8,388,608 rounds. Immediately
after Hash generation all Variables containing plain password fragments are
deleted. Password file SHOULD be '0400' and 'root:root' and is deleted without
further prompt after password hash has been successfully generated via:
'shred -vfzu 5 -f'.
No tracing of any plain text password fragment in any debug log.
$(echo -e "\e[97m --ssh-port <INTEGER>\e[0m")
The desired Port SSH should listen to.
If not provided defaults to Port 22.
$(echo -e "\e[97m --ssh-pubkey </path/to/.ssh/>\e[0m")
