Add dracut(8) support
Add support for the dracut(8) system for generating initramfs image
files; dracut is an alternative to the "initramfs-tools" package.
* .bzrignore (dracut-module/password-agent): Ignore new binary file.
* dracut-module: New directory for the dracut module.
* INSTALL (Prerequisites/Libraries/Mandos Client): Add dracut as an
alternative to
initramfs-tools,
and also add GLib.
* Makefile (DRACUTMODULE, GLIB_CFLAGS, GLIB_LIBS): New.
(CPROGS): Add "dracut-module/password-agent".
(DOCS): Add "dracut-module/password-agent.8mandos".
(dracut-module/password-agent.8mandos): New.
(dracut-module/password-agent.8mandos.xhtml): - '' -
(dracut-module/password-agent): - '' -
(check): Add command to run tests of password-agent(8mandos).
(install-client-nokey): Also install the dracut module directory,
its files, and the password-agent(8mandos)
manual page.
(install-client): To update the initramfs image file, run
update-initramfs or dracut depending on what is
installed.
(uninstall-client): - '' - and also uninstall the the files in the
dracut module directory, that directory itself,
and the password-agent(8mandos) manual page.
* debian/control (Build-Depends): Add "libglib2.0-dev (>=2.40)".
(Package: mandos-client/Depends): Add "dracut (>= 044+241-3)" as an
alternative dependency to
initramfs-tools.
(Package: mandos-client/Conflicts): New; set to
"dracut-config-generic".
(debian/mandos-client.README.Debian): Document alternative commands
to update the initramfs image
for when dracut is used.
* debian/mandos-client.postinst (update_initramfs): Use alternative
commands to update
the initramfs
image for when
dracut is used.
* debian/tests/control (password-agent, password-agent-suid): Add two
new tests.
* dracut-module/ask-password-mandos.path: New.
* dracut-module/ask-password-mandos.service: - '' -
* dracut-module/cmdline-mandos.sh: - '' -
* dracut-module/module-setup.sh: - '' -
* dracut-module/password-agent.c: - '' -
* dracut-module/password-agent.xml: - '' -
* initramfs-unpack: Use the dracut "skipcpio" command, if available.
Also be more flexible and try hard to detect where
compressed data starts.
* plugins.d/mandos-client.xml (SECURITY): Be more precise that the
mandos-client binary might
not always be setuid, but
that the program assumes
that it has been started
that way.
* plugins.d/password-prompt.c: Add new "--prompt" option.
(conflict_detection): First try to detect the new PID file of
plymouth.
(main): Define and use new "prompt" variable.
* plugins.d/password-prompt.xml (SYNOPSIS): Show new --prompt option.
(DESCRIPTION): Describe new behavior of looking for plymouth PID
file.
(OPTIONS): Document new "--prompt" option.
(ENVIRONMENT): Clarify that the CRYPTTAB_SOURCE and CRYPTTAB_NAME
environment variables are not used if the --prompt
option is used. Remove unnecessarily specific
details about where the CRYPTTAB_SOURCE and
CRYPTTAB_NAME comes from, since this can now be
either initramfs-tools or dracut.
(SEE ALSO): Remove superfluous crypttab(5) reference, and add commas
to separate the other references.
* plugins.d/plymouth.c: Add new "--prompt" and "--debug" options.
(debug): New global flag.
(fprintf_plus): New function, used for debug output.
(exec_and_wait): Add extra "const" to "argv" argument.
(main): Define and use new "prompt" variable. Add debug output.
(main/options, main/parse_opt): New; used to parse options.
* plugins.d/plymouth.xml (SYNOPSIS): Show new options.
(OPTIONS): Document new options.
(ENVIRONMENT): Clarify that the cryptsource and crypttarget
environment variables are not used if the --prompt
option is used. Remove unnecessarily specific
details about where the cryptsource and crypttarget
comes from, since this can now be either
initramfs-tools or dracut.
(EXAMPLE): Add an example using an option.
(SEE ALSO): Remove superfluous crypttab(5) reference.
* plugins.d/splashy.xml (ENVIRONMENT): Clarify that the cryptsource
and crypttarget environment
variables are not used if the
--prompt option is used.
Remove unnecessarily specific
details about where the
cryptsource and crypttarget
comes from, since this can now
be either initramfs-tools or
dracut.
(SEE ALSO): Remove superfluous crypttab(5) reference.
* plugins.d/usplash.xml (ENVIRONMENT): Clarify that the cryptsource
and crypttarget environment
variables are not used if the
--prompt option is used.
Remove unnecessarily specific

cryptsource and crypttarget
comes from, since this can now
