[Bug 1651818] Re: busybox-initramfs needs different compile options to work with cryptroot-unlock

[Linuxrider]

Well of course it is not the default unlocking mechanism.
In my setup cryptroot-unlock is used to unlock remotely over dropbear.
Most probably the regex can adapted. But I have no experience with that.

When I encountered the issue I tested the script with standard busybox and it
worked. Then I compared the config of the two packages and found the two parameters
to be essential. It was the easiest way for me.
Of course I did not check for other side effects of the change.

A second command is not working with the initramfs busybox. It's "grep -Ez".
The z option is not present.

  cryptroot-unlock

Status in busybox package in Ubuntu:
  Confirmed
Status in cryptsetup package in Ubuntu:
  Confirmed

Bug description:
  The cryptroot-unlock script in the cryptsetup package does not work in initramfs.
  It fails because "ps -e" is not available in busybox for initramfs.
  When building the package with

  CONFIG_DESKTOP=y
  CONFIG_EXTRA_COMPAT=y

  the needed commands (ps, grep) with parameter are there and it works.
  Tetsted on Ubuntu GNOME 16.10.
