Subject: [PATCH v2] defaultenv: boot/net: Boot initramfs from tftp if present
Date: Wed, 11 Nov 2015 11:13:42 +0100	[thread overview]
Message-ID: <1447236822-13102-1-git-send-email-mpa@pengutronix.de> (raw)

Use an 'initramfs' file if it exists instead of nfsroot. This offers the
possibility to quickly boot complete filesystems as initramfs without
the need to flash an SD-card or similar. If the initramfs does not
exist, it uses the default nfsroot mechanism.

Signed-off-by: Markus Pargmann <mpa@pengutronix.de>

Changes in v2:
- Changed variable name to 'initramfs' to make clear that this is intended to
  be used for initramfs. initrd is possible but requires additional linux
  bootargs
- Removed the hardcoded 'rdinit' bootarg
