Where is the notify command run?
I'm reading the usage docs here.
The --notify-command=COMMAND option is optional. The given COMMAND will be run whenever cryptops-api detects that the root device needs the user to enter their password to continue the booting process. You can use this to notify the user of this situation.
Where is this command run? As in, does it get run in the busybox shell? Is it run on some other server? I'm wondering what commands are available in the $PATH or how I can figure out which commands are at my disposal in this context. Can I use curl? Or wget? Or is there an email client that would allow me to send emails? Do I need to provide my own SMTP transport? Etc...
