#
#  Creates a minimalistic runlevel 2 root filesystem with getty.  
#  Tested on Debian unstable/testing,  but should work on other distributions 
#  (Mandrake,  RedHat, etc.) by using the proper inittab (edit) and getty.
# 
#  Create either as a normal user or root.  When using genext2fs it's necessary to specify a
#  root filesystem size larger than the actual size because genext2fs uses different accounting
#  information than mke2fs.
#
#  Works both with and without devfs, i.e devfs=nomount.

#
# 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 concern themselves
#     with the service modules or libraries involved.  The new behavior is recommended, 
#     but if the old behavior is desired switch 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.

##### INITTAB and GETTY
# Use one of these pairs, based on your distribution:
#  Remember these aren't absolutely necessary.
#
#===== DEBIAN (1.1) uses a program called "getty" which is actually 
#                  agetty in disguise:
/etc/inittab	<= Replacements/etc/inittab.debian-min
/sbin/getty
#
#
#===== REDHAT (5.x, 6.0) uses getty
#/etc/inittab	<= Replacements/etc/inittab
#/sbin/getty
#
#
#===== MANDRAKE (7.0, 8.0) uses mingetty
#/etc/inittab	<= Replacements/etc/inittab.mingetty
#/sbin/mingetty
#
#
#===== SLACKWARE uses agetty:
#/etc/inittab	<= Replacements/etc/inittab.agetty
#/sbin/agetty
#
#
#===== SUSE	uses mingetty:
#/etc/inittab    <= Replacements/etc/inittab.mingetty     
#/sbin/mingetty
#
#
# If in doubt, check your /etc/inittab.
#
# In any case, check to make sure the *getty* calls in the inittab match
# the executable you're using.  Yard can't check this and *getty* will
# hang if the arguments are wrong.

# Devices - for devfs=nomount the bare minimum required is an inital console, otherwise
# nothing is required.
