#
# Creates a minimalistic multi-user runlevel root filesystem with getty.
# Tested on Debian unstable/testing, but should work on other distributions
# (Mandrake, RedHat, Slackware, etc.) by using the proper inittab and getty.
#
# Create either as a normal user or root.
#
# Works both with and without devfs, i.e devfs=nomount, assuming the correct
# replacement inittab is used. In order to create a non-devfs from a host
# system using devfs, either manually mknod /dev/tty[0-2] (major 4 minor 0-2)
# or have devfsd automatically make these devices every time the root
# filesystem starts.

#
# Format rules:
# - Lines beginning with # or % are comments.
#
# - Blank lines and whitespace are ignored.
#
# - Lines of the form "filename1 -> filename2" will create symbolic (soft)
# links on the root fs. For example, if you want sh linked to ash
# in the root fs you could specify: "/bin/sh -> /bin/ash".
# The literal output from the last column found when using `ls -s`
# may be used, or fictional links may be created, for instance,
# ashsa -> bash (In this case if /bin/bash exists on the system the link
# would be /bin/ashsa -> /bin/bash, otherwise /asha -> /bash)
# (There is no way to specify hardlinks, though hard linked files
# that exist on the hard disk will be hard linked.)
#
# - Lines of the form "filename1 <= Replacements/pathto_filename2"
# will cause filename2 to be copied to filename1 on the root fs.
# This is useful for specifying trimmed-down replacements for
# /etc/passwd, /etc/inittab, etc. For the above example, filename2
# is found in its real path below the Replacements directory which is
# found in the default Replacements path of $HOME/yard/Replacements.
# Replacements may be specified in their absolute or relative paths
# (found using $PATH).
#
# - User defined paths may be specified in the Path Box
# (Edit->Settings->Path). These paths may be used to search for the
# relative paths for Replacements, links and files.
#
# - Glob designations (?, * and []) are generally allowed, eg /dev/hd[ab]*
# Wildcards are not allowed in link specs or replacement specs.
#
# - The $RELEASE variable which may be used to locate the modules directory
# can come from one of three sources, the kernel version returned from a
# selected kernel in the main section,
# a user defined kernel version in the ABS, or the value of `uname -r`
# returned automatically when the other two sources aren't specified.
#
# You don't need to specify shared libraries or loaders because
# necessary libraries are detected automatically.
# You may choose between two behaviors for the treatment of NSS and PAM
# libraries. The old Yard behavior assumes that only the user knows which
# service modules they want to include in the file set, and tests
# (see Tests menu) may be run on the configuration files to show what isn't
# provided, so that the user can include the missing modules manually by
# editing the template, but the user still needs to figure out any
# dependencies since the modules are dynamically loaded.
#
# The new Yard behavior (default) assumes that the user does know what they
# want based on what the user puts in the NSS (nsswitch.conf) and PAM
# (pam.conf or pam.d/*) configuration files. The configuration files are
# then parsed and the corresponding service modules are included in the
# file set if they exist on the host system, tests (see Tests menu) can be
# run to find out which ones don't exist. The service modules are checked
# for library dependencies. What this means is that the user only needs
# to specify the configuration files in the template, and doesn't need to
# be concerned with the service modules or libraries involved. The new
# behavior is recommended, and won't effect the file set even if the
# requirements are already included in the template. If desired, the old
# behavior may be regained by switching off Edit->Settings->"NSS Conf"
# and Edit->Settings->"PAM Conf".
#
# You don't need to explicitly specify intermediate directories unless you
# just want to make sure they exist.
