+early-ssh is a simple initramfs hook, which installs Dropbear SSH server
+into your initramfs, and starts it at boottime, so you will be able to
+do a lot of things remotely over SSH, before your root partition gets
+mounted, for example:
+
+* unlocking LUKS encrypted crypto devices - even your root can be an
+  encrypted filesystem
+* assembling/altering RAID arrays (mdadm)
+* checking the root filesystem in read-write mode, taking action in case
+  of errors
+* and so on...

+You will need to adjust how you generate your initrd to include
+early-ssh and to start it at the correct time.
+
+Example for LUKS + LVM as described in README_CRYPT.TXT:
+
+mkinitrd -c -k "$kernel" -f ext4 -r /dev/disk/by-uuid/<some uuid> \
+  -m ext4:<more modules> -u -L -o /boot/initrd-"$kernel".gz \
+  -C /dev/disk/by-uuid/<some other uuid>
+  -s /tmp/initrd-tree-"$kernel"
+
+# clear the luksdev so init does not try to unlock it itself
+true > /tmp/initrd-tree-"$kernel"/luksdev
+DESTDIR=/tmp/initrd-tree-"$kernel" /usr/share/mkinitrd/hooks/early_ssh
+sed -i '/^[[:space:]]*if \[ -x \/sbin\/cryptsetup \]/i \
+  \/early_ssh' /tmp/initrd-tree-"$kernel"/init
+
+mkinitrd -k "$kernel" -f ext4 -r /dev/disk/by-uuid/<some uuid> -u -L \

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.

+early-ssh:
+early-ssh: early-ssh gives you an SSH server during the boot of your Linux
+early-ssh: system. It starts before the root filesystem is mounted so you can
+early-ssh: unlock your encrypted root filesystem interactively, you don't have
+early-ssh: to be at the console of your server. You can also scp files to your
+early-ssh: server so you can even start your key-encrypted system.
