| Usage: mk-sysimage | [OPTION]...  basedir |
basedir should be the root of the client's linux image.
Options:
| -d, | -dryrun | Preview changes |
| -r, | -revert | Revert all files and services back to normal |
| -c, | -config=FILE | Specify alternate configuration file |
| -p, | -patchfile=FILE | Specify alternate distribution patch |
| -sp, | -skippatch | Skip distribution patch |
| -q, | -quiet | Suppress output |
The mk-sysimage script reads the oneSIS
configuration file, /etc/sysimage.conf, and alters components
of the filesystem for oneSIS to operate correctly. It creates some
directories, applies the patch file for the specific distribution
(see section
4.6), and performs other helpful tasks.
Several directives in /etc/sysimage.conf require
altering a file in the image to point to its corresponding location
in /ram.
mk-sysimage creates any new symbolic links to /ram
and the corresponding `.default' files or directories.
mk-sysimage automatically restores files in the master
image to their original state when they are removed from the
configuration. It can also revert the entire filesystem back to its
original state with
the -revert option.
To ensure that configuration changes are reflected in the system
image, it is recommended that the mk-sysimage script be run
after changing
any LINK* directives in the configuration.
For an image located in /var/lib/oneSIS/image, mk-sysimage would be run with:
Note: mk-sysimage will attempt to patch the target
distribution every time it is run. A warning will be displayed
unless a patch exists for the distribution or the -skippatch
option is supplied. This is meant to encourage anyone hacking the
rc scripts of a new distribution to
develop a patch for it and feed that back to the oneSIS community.
Warning: If you manually alter your distribution's rc scripts, mk-sysimage will fail to apply the distribution patch and display long error messages. If you plan to do this, you can run mk-sysimage with the -skippatch option so it doesn't try re-patch the distribution.
