Feature request: Support for Nwipe configuration file, /etc/nwipe/nwipe.conf

[Aterfax]

https://github.com/martijnvanbrummelen/nwipe/releases/tag/v0.35

Nwipe now has a configuration file, /etc/nwipe/nwipe.conf. This is currently used to store PDF parameters but will be enhanced over the next versions to include default wipe parameters amongst other additions.

As part of generating erasure certificates, some configuration options are stored in the /etc/nwipe/nwipe.conf file. Similarly to nwipe_options="", we could do with a method for providing settings directly from the boot APPEND line so settings can be applied during netboots.

It may make sense for this configuration file to be supplied as a URL to CURL/wget download a configuration and use it, or simply as some form of inline.

Incidentally, the documented lftp="" lines can also be amended to copy these certificates back to an FTP server with the additional command mput *.pdf

e.g.

lftp="open 192.168.1.250; user shredosuser password12345; cd upload; mput nwipe_*.txt; mput *.pdf"

Thanks for the reminder re lftp, I'll make the changes for that.

I might need some clarification regarding the boot append line. Do you mean have a typical grub boot menu where you can edit the command line from the grub menu?

Apologies, this wasn't clear.

The APPEND line I refer to would be in the PXE boot configs, e.g.

DEFAULT menu.c32
PROMPT 0
TIMEOUT 200
ONTIMEOUT shredosautonuke
MENU TITLE ShredOS Autonuke 3 Pass

LABEL shredosautonuke
  MENU DEFAULT
  KERNEL shredos/shredos
  # Fully automatic formatting of ALL DISKS
  APPEND console=ttyS0,9600n8 loglevel=3 nwipe_options="--autonuke  --autopoweroff --nousb --method=dodshort --rounds=1 --verify=last" lftp="open 192.168.1.250; user shredosuser mypassword; cd upload; mput nwipe_*.txt; mput *.pdf"

e.g.

We could have a new nwipe_config_url="https://mydomain.com/nwipe.conf" and amend to:

  APPEND console=ttyS0,9600n8 loglevel=3 nwipe_options="--autonuke  --autopoweroff --nousb --method=dodshort --rounds=1 --verify=last" nwipe_config_url="https://mydomain.com/nwipe.conf" lftp="open 192.168.1.250; user shredosuser mypassword; cd upload; mput nwipe_*.txt; mput *.pdf"

I was just meaning to get at the fact we're going to need to pass this info during the netboot process as part of a command, so we're going to need another kernel line compatible argument like nwipe_options= to be passable.

Or in the ipxe parlance from Netboot.xyz

Thanks for the clarification. I'll add this into the next point release 25.1 with the other changes/additions I'm currently making.
