Package: initramfs-tools
Version: 0.91e
Severity: wishlist
Tags: patch
this patch is part of three patches (initramfs-tools, cryptsetup,
dropbear) which enable mkinitramfs to create initramfss that provide the
ability to log in and unlock a cryptroot during the boot process from
remote via ssh.
calling configure_networking from /scripts/functions might appear more
than once, so just try if it hasn't been done/wasn't successful yet.
check that by testing for existence of /tmp/net-$DEVICE.conf which is
created by ipconfig.
in mkinitramfs CONFDIR is exported, as this is necessary for hooks (see
related dropbear patch) to find the config without relying on something
hardcoded that's otherwise (mkinitramfs) dynamic.
