-=head1 NAME
-
-febootstrap-to-initramfs - Convert febootstrap root to initramfs (cpio) file.
-
-=head1 SYNOPSIS
-
- febootstrap-to-initramfs [--files=filelist] DIR > initrd.img
-
-=head1 DESCRIPTION
-
-I<febootstrap-to-initramfs> converts the filesystem created by
-L<febootstrap(8)> into an initramfs image. This allows the new system
-to be booted on real hardware or inside a QEMU-based virtual machine.
-
-An initramfs image is just a compressed cpio file, so you could
-uncompress it with L<gunzip(1)> and use L<cpio(1)> to convert it into
-other formats.
-
-The permissions inside the initrd image are corrected automatically
-(see the discussion of fakeroot logfile in the L<febootstrap(8)>
-page). You do I<not> need to run this command as root.
-
-=head1 OPTIONS
-
-=over 4
-
-=item --files=filelist
-
-C<filelist> should be a file containing a list of the files to be
-added to the initramfs (one per line). Only those files are added and
-any others are ignored.
-
-When the C<--files> option is not given, all files in C<DIR> are added
-to the initramfs image.
-
-=item --nocompress
-
-This prevents the initramfs image from being compressed.
-
-Linux can boot from uncompressed initramfs images (in fact, faster),
-but they take up a lot more space on disk.
-

-
-=head1 /init
-
-Normal initramfs images start by executing the program or script
-called C</init>. febootstrap does not create this script, so you may
-wish to, particularly for very minimal bootstraps that don't have the
-normal SysVinit/upstart machinery. It's also required if the kernel
-cannot find a "real" root filesystem (the root filesystem that we
-built and placed in an initramfs doesn't count).
-
-Linux will try to run the following commands in turn, unless you
-override it using the C<init=I<cmd>> kernel option:

-
-=head1 MEMORY REQUIREMENTS
-
-Initramfs images are uncompressed by the kernel into memory. When
-booting the new system you will need at least enough free RAM to store
-the B<uncompressed> filesystem plus extra to run any programs. Bear
-this in mind when creating very large filesystems.
