Description of Anaconda Install Methods (and ways of updating it)
-----------------------------------------------------------------
Notes:
------------
- "fully exploded tree" - this is a tree which in the root has the
the 'RedHat' directory from every CD image merged into a single
'RedHat' directory.
- "ISO" - the ISO image for a CD image.
- "anaconda update" - patches for anaconda to fix bugs/etc
- all paths without a leading '/' are relative to directory specified
to installer containing install source.
- 'updates.img' is a ext2 filesystem containing the updated python
sources and modules for anaconda.
Current Installation Methods:
-----------------------------
- CDROM
-------
Summary:
This is pretty self-explanatory. Mounts the CD and installs packages,
prompts user to switch CDs when the next disc is required.
Update Options:
- floppy.
- 'updates.img' file in '/RedHat/base' directory of CD #1 image.
- updated python sources or modules in 'RHupdates/' directory of
CD #1 image are used in preference to those in original.
- NFS (from a fully exploded tree)
----------------------------------
Summary:
Mounts directory from NFS server.
Update Options:
- floppy.
- 'updates.img' file in 'RedHat/base' directory.
- updated python sources or modules in 'RHupdates/' directory are
used in preference to those in original.
- NFS (from a directory of ISOs)
--------------------------------
Summary:
Loopback mounts ISO images from NFS server.
Update Options:
- floppy
- 'updates.img' file in 'RedHat/base' directory
- updated python sources or modules in 'RHupdates/' directory are
used in preference to those in original.
- FTP/HTTP (from a fully exploded tree)
---------------------------------------
Summary:
Pulls files from tree via FTP.
Update Options:
- floppy.
- 'updates.img' file in 'RedHat/base' directory.
- FTP/HTTP (from a directory of loopback-mounted ISOs)
------------------------------------------------------
Summary:
Pulls files from tree via FTP. Looks in 'disc1/' directory to contain
files from CD #1, 'disc2/' for CD #2, etc. These can be created on the
server by loopback mounting the ISO images into these directories under
the directory made available to ftp.
Update Options:
- floppy
- 'updates.img' file in '/RedHat/base' directory in ISO image for CD #1.
Hard Drive from fully exploded tree (kickstart only)
----------------------------------------------------
Summary:
Similar to NFS method - user specifies a top-level directory and
all files are sought under there.
Update Options:
- floppy.
- 'updates.img' file in '/RedHat/base' directory.
- updated python sources or modules in 'RHupdates/' directory are
used in preference to those in original.
Hard Drive from ISOs (non-kickstart only)
-----------------------------------------
Summary:
Similar to NFS ISO-based method - loopback mounts ISOs in directory
specified by user.
Update Options:
- floppy.
- 'updates.img' file in '/RedHat/base' directory of ISO image for CD #1.
- updated python sources or modules in 'RHupdates/' directory are
used in preference to those in original.
