Configuring the PicoBSD install floppy
Configuring the PicoBSD install floppy
The PicoBSD Install Floppy is engineered to be flexible since every
site has their own needs for an automated install solution. The
base package contains tools and frameworks for further
customization.
Generating an Install Image
Central to the design of the install floppy is a tarball image of
the operating system. The install floppy downloads and extracts
the image from a master server.
To generate the install image:
- Install and configure a machine as it should be
installed.
- Make the template machine as close to the target
machines as possible. System-specific files such as
/etc/fstab can cause problems if they are
specific to a particular disk setup, such as multiple SCSI
disks in the template vs. single IDE disks in the target.
- Try to keep the template as small as practical.
The more packages you install on the template, the larger
the image becomes.
- Use tar to create the image. This shell script is useful
for automating the process.
#!/bin/sh
TARBALL="/fbsdimage.tgz"
GZIP="-9"
tar -cpvzf ${TARBALL} --totals --exclude '/proc/*' --exclude '/var/tmp/*' \
--exclude '/var/log/*' --exclude '/tmp/*' --exclude '/fbsdimage.tgz' /
- Use the '--exclude' argument to remove files from the
image.
- Don't forget to exclude the image itself or your tarball
will be much larger than it should.
- The GZIP environment variable sets arguments to the
gzip command called by tar's z option.
- Copy the image file to your load server into a public FTP
directory.
Configuring the Install Floppy
Once the install floppy has been built using the PicoBSD build
script, mount the floppy and modify the install
script, /floppy/etc/doinstall. doinstall is
called from rc on startup to install the disk image and perform
whatever other setup tasks are necessary. The script can set
network parameters, configure applications, select kernels, or
whatever else a shell script can do. A handful of useful
utilities is included on the disk to ease automated installation.
At minumum, set the URL to the FTP server holding the disk
image. If you wish, uncomment and modify to taste any of the
code blocks provided.
By default, the install floppy:
- Creates one large FreeBSD slice on the first IDE disk (wd0).
- Creates a 256MB swap partition and the rest for a large
root partition.
- Formats the large partition using newfs with
default parameters. '
- Downloads the image via FTP and feeds it directly into
cpio for extraction.
To modify the disk formatting parameters, modify the
/floppy/etc/prepdisk script. prepdisk is a
simple awk script that feeds directly into disklabel.
Simply edit the generated partition table to taste.
