  228. # DESCRIPTION
  229. # This script makes a copy of your system with rsync and then creates
  230. # an iso file to be used as a live-cd. There are options in the config
  231. # file to change the location of the copy and the location of the final
  232. # iso file, in case there's not enough room on the system drive. Read
  233. # the config file for more options. (/etc/refractasnapshot.conf)
  234. #
  235. #
  236. #
  237. # If you want to change any defaults, change them in the configfile.
  238. # Default is /etc/refractasnapshot.conf
  239. # If you want to use a different config file for testing,
  240. # either change this variable here or use the -c, --config option on
  241. # the command-line. (Command-line option will supercede this setting.)
  242. # Normally, users should not edit anything in this script.
  243. #
  244. configfile="/etc/refractasnapshot.conf"

  1585. within the debfile, the to-be-installed copy of
  1586. /usr/share/doc/refractasnapshot-base/README (is from v10.0, so not entirely up-to-date).
  1587. Below, I'm pasting the content of
  1588. /usr/share/doc/refractasnapshot-base/readme.refractasnapshot.txt.gz
  1589.  
  1590. v. 10.2.0+
  1591. Refracta Snapshot creates a bootable live-CD image which is a copy of
  1592. your running system. Any changes you make to the running system,
  1593. including desktop preferences, configuration changes, or added software
  1594. will be copied to the snapshot and will be present when you run that
  1595. snapshot as a live system.
  1596.  
  1597. See the config file, /etc/refractasnapshot.conf for setting options.
  1598. The config file is the most up-to-date and detailed documentation.
  1599.  
  1600. See the excludes file, /usr/lib/refractasnapshot/snapshot_exclude.list
  1601. to examine which files and directories will not be copied to the
  1602. snapshot. Edit the file as needed, either by adding items or commenting
  1603. out listed items that you want copied.
  1604.  
  1605. As of version 9.0.8, you can edit the config and excludes files from
  1606. within the gui program by choosing "Setup".
  1607.  
  1608. To run the script:
  1609.  
  1610. refractasnapshot
  1611. or
  1612. refractasnapshot-gui
  1613.  
  1614. or use the full path if needed:
  1615. /usr/bin/refractasnapshot(-gui)
  1616.  
  1617.  
  1618. COMMAND LINE OPTIONS
  1619.  
  1620. -h, --help show help
  1621. -v, --version display the version information
  1622. -c, --config specify a different config file
  1623. (file name must be next argument)
  1624. -d, --debug run in debug mode (set -x)
  1625.  
  1626.  
  1627. TROUBLESHOOTING
  1628.  
  1629. Run refractasnapshot or refractasnapshot-gui with the '-d' option and
  1630. save /var/log/refractasnapshot.log for analysis.
  1631.  
  1632.  
  1633. NOCOPY OPTION
  1634.  
  1635. The nocopy option has been replaced with an options menu in the script.
  1636. 1. Create a snapshot
  1637. - This runs the full process to create a snapshot, consisting of
  1638. rsync copy to create the live filesystem
  1639. copy isolinux boot files
  1640. create efi boot files
  1641. squash the live filesystem
  1642. put it all into a bootable iso file.
  1643. 2. Re-squash and make iso (no-copy)
  1644. - For manual changes to the live filesystem in $work_dir/myfs.
  1645. 3. Re-make efi files and iso (no-copy, no-squash)
  1646. - Maybe for hacking on the mkefi function in the script.
  1647. 4. Re-run xorriso only (make iso, no-copy, no-squash)
  1648. - For manual changes to any files in the root of the live media,
  1649. such as boot menus or boot help files in $work_dir/iso.
  1650.  
  1651. The nocopy options will prevent rsync from updating the saved copy of the
  1652. filesystem. Any system changes or updates that occurred after the copy
  1653. was made will not be included in the final image.
  1654.  
  1655. The nocopy options are for special purposes (for example, you made changes
  1656. to the saved copy of the filesystem after a previous snapshot, and you
  1657. don't want those changes overwritten by the running system.)
  1658. However, you must have save_work=yes and have a previously saved copy of
  1659. the filesystem for nocopy to work.
  1660.  
  1661.  
  1662. CREATING A SNAPSHOT FROM AN ENCRYPTED SYSTEM OR SWAP PARTITION
  1663.  
  1664. If your host system is encrypted or has a swap partition, the script
  1665. will edit the snapshot's initrd to remove conf/conf.d/cryptroot and/or
  1666. conf/conf.d/resume so that the snapshot iso will boot successfully.
  1667.  
  1668. This will NOT affect the initrd on the host system.
  1669.  
  1670.  
  1671. CREATING A SNAPSHOT TO BE USED WITH ENCRYPTED PERSISTENCE
  1672.  
  1673. If you want to create an iso that will be used to make a live-usb with
  1674. an encrypted volume for persistence, you need to rebuild the initrd to
  1675. include cryptsetup if it's missing. This is now automatic.
  1676.  
  1677. - Uncomment the line in /etc/refractasnapshot.conf that contains:
  1678. initrd_crypt="yes"
  1679.  
  1680. The script will check for cryptsetup in the initrd, and if necessary
  1681. will edit /etc/cryptsetup-initramfs/conf-hook to set CRYPTSETUP=y.
  1682.  
  1683. This DOES change the host's initrd. To revert the change in the host,
  1684. comment out the line and run 'update-initramfs -u'.
  1685.  
  1686. Assumptions: The kernel you're running is the one that you will use in
  1687. the snapshot. (i.e. /initrd.img)
  1688.  
  1689.  
  1690. NETWORK CONFIGURATIONS
  1691.  
  1692. If you want custom network configurations to be copied into the snapshot,
  1693. uncomment the line in the config file that has:
  1694. netconfig_opt="ip=frommedia"
  1695.  
  1696. This will preserve your /etc/network/interfaces and any saved wireless
  1697. configurations. This works for NetworkManager, simple-netaid/netman
  1698. and wicd. It will also add "ip=frommedia" to the boot command, so that
  1699. the saved configuration will be used in the live system.
  1700.  
  1701. If you leave the line commented, the default behavior is to
  1702. replace the interfaces file with one that only has the loopback interface
  1703. configured and to delete any saved wireless configurations.
  1704. (This only affects the filesystem copy in $work_dir/myfs.)
  1705.  
  1706. NOTE!!! If you're using some other network manager, and you don't want
  1707. your configs to be copied, you need to add the appropriate files to
  1708. the excludes list. (Tell me what those files are, and I'll fix
  1709. refractasnapshot to handle it.)
  1710.  
  1711.  
  1712. NETWORK INTERFACE NAMES
  1713.  
  1714. To control whether the snapshot uses old network interface names like
  1715. eth0 or new names like enp0s1, uncomment and set ifnames_opt in the
  1716. config file.
  1717.  
  1718. Use net.ifnames=0 to force old interface names with udev. (eth0)
  1719. Use net.ifnames=1 to force new interface names with eudev. (enp0s1)
  1720.
