Turn the rc.d symlinks for the guestfs-firstboot service as relative,
instead of absolute paths: the result is the same (the service works the
same), and this way is more coherent with symlinks created by
update-rc.d.
Currently we install a systemd service named firstboot.service and a
SysV service named virt-sysprep-firstboot. On systems where systemd is
the init system and runs with the SysV compatibility, the different
names make systemd handle them as different services, and thus trying to
run the firstboot script runner twice.
Rename both the systemd service and the SysV one to guestfs-firstboot:
the new name is less generic, and allows the systemd service to be
shadowed by the SysV service (and thus running just once).
Also cleanup the old services: the old SysV service can be removed
directly, since its former name had "virt-sysprep" in it, and so there
could not be much room for confusion and conflict. Regarding the old
systemd service: to avoid leaving it behind, a simple cleanup strategy
is in place, checking the content of the old firstboot.service to really
ensure we are removing one of our versions of this file.
ocamlmklib -g does not work in OCaml 4.01.0. It does work (and is
desirable) in OCaml 4.02.2. However since we would like to support
back to OCaml 3.11, we cannot use it.
In libguestfs 1.33.43 we managed to release a completely
non-functional virt-customize binary (it ran without error but did
nothing at all, whatever command line arguments you gave it).
Improve the test so this cannot happen again.
podcheck.pl is run as part of the tests to perform various checks on
the documentation and the tool.
Currently we check only that the documented options matches the
options that the tool implements and vice versa. This commit would
also allow us (in future) to check --help, --long-options,
--short-options, --version output.
This commit includes scripts to run the tests and various fixes to the
manual pages to ensure that the tests pass.
Instead of linking with individual objects, which is very tedious,
build a proper library and link virt-builder, virt-customize and
virt-sysprep to it.
This makes the binaries a tiny bit smaller because .cmxa/.a files
allow unused code to be removed by the linker, whereas explicitly
linking .cmx/.o files does not.
Instead of linking with individual objects, which is very tedious,
build a proper library and link the other tools with it.
This doesn't make the resulting binaries any larger.
This implements the --selinux-relabel option for virt-customize,
virt-builder and virt-sysprep. There is no need to autorelabel
functionality now.

Since the function uses the StringMap module, I also had to
move this to mllib.
The function is renamed and the 'if verbose ()' part is moved into the
function, but apart from that, it's all just code motion.
Add a new Getopt module to mllib, to parse command line arguments with
handlers close to the ones used with Arg, but using getopt(3) (actually
getopt_long_only) to do the real parsing. This allow us to provide
options for OCaml tools with a syntax similar to the C tools, and use
the additional features getopt offers and Arg does not.
Getopt now handles every part of the command line handling, including
the output of short & long options.
Do a single-step conversion of Common_utils and all the OCaml tools to
the syntax of Getopt.
Move a couple of utility functions from Common_utils to Getopt, since
they fit better there (and Common_utils cannot be used in Getopt, as
the former already uses the latter).
As side-change due to the conversion, extra arguments for sysprep
operation can have more keys for the same argument.
This option (alternately spelled: --color, --colour, --colors, or
--colours) enables ANSI colour sequences output even if that would be
disabled becaues the output is not a TTY.
OCaml 4.02 introduced the 'bytes' type, a mutable string intended to
replace the existing 'string' type for those cases where the byte
array can be mutated. In future the 'string' type will become
immutable. This is not the default now, but it can be forced using
the '-safe-string' compile option.
This commit changes the code so that it could be compiled using
'-safe-string' (but does not actually make that change).
If we detect OCaml < 4.02, we create a dummy 'Bytes' compatibility
module ((nearly) an alias for the 'String' module). The only
significant difference from upstream OCaml is that you must write the
'bytes' type as 'Bytes.t' in interfaces, apart from that everything
else should work.
In commit ae6f726ecc we started to use
the virt-customize code to replace various virt-sysprep operations.
This had the effect of adding many more possible operations to
virt-sysprep, but some of them (specifically --install) did not work
unless the appliance network is enabled. It was not enabled in
virt-sysprep, so these operations never worked.
This change does NOT enable the network by default. However it adds a
--network flag which may be used in conjunction with --install etc to
make those commands work.
In addition we now emit a warning for certain customize operations if
they fail and if the network is not enabled. It will print:
[ 4.5] Installing packages: tcpdump
Error: Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infra=stock error was
virt-sysprep: warning: the command may have failed because the network is
disabled. Try either removing '--no-network' or adding '--network' on the
command line.
virt-sysprep: error: yum -y install 'tcpdump': command exited with an error
(If the network is already enabled, or if the command is successful,
then the warning is not printed.)

Returns true if the device is a host partition.
The only tedious bit of this patch is that now Common_utils depends on
Dev_t so we have to add extra objects every time something links with
Common_utils.
Sync the windows firstboot script with its linux brother. Also change
the main redirection to append to the log rather than overwriting it.
With this change, the firstboot script will resist reboots in the
executed scripts.
Add a common debug function for printing debugging messages. It only
emits the debug message when the verbose (-v) flag is used on the
command line.
It sends the output to stderr, which is flushed immediately after the
message is printed (to help with debugging unexpected crashes). There
are good arguments for sending the debug to either stdout or stderr,
and almost all existing debug messages replaced by this change went to
stdout. However using stderr is consistent with libguestfs's own
debug messages which also go to stderr.
I only made simple changes to code of the form 'if verbose () then
printf ...'. There are more places which could be changed in future.
In a few places I removed gettext calls since we probably should not
translate debug messages.
It is still only emitted if we are debugging in order not to cause
unnecessary alarm. Note this code needs a better long term fix, this
is still a hack.
Only in very recent OCaml versions (or in Fedora) the Arg module
supports the --foo=bar syntax for options with arguments. Do not
require it yet.
Fixes commit 64bb9edd52.
When possible, make the disk image format explicit when invoking tools
or using add-drive. This avoids warnings from qemu about the unspecified
format for the image, and also makes qemu slightly faster (skipping the
disk image probing).
Tests checking the image probing are not touched.
This changes also:
- old-style invocations of tools (`$tool $filename`) into new style
(`$tool -a $filename`)
- add-drive-ro/add-drive-with-if guestfish commands into add/add-drive
with explicit readonly/iface arguments
There should be no change in the tests results.
Turn the snippet reading user information from /etc/passwd in a slightly
more generic function, so there is no need to copy&paste for other
details.
Mostly code motion.
For Windows, we now print:
$ virt-customize -a ./test-data/phony-guests/windows.img --install MSSQL
[ 0.0] Examining the guest ...
[ 14.2] Setting a random seed
virt-customize: warning: random seed could not be set for this type of
guest
[ 14.2] Installing packages: MSSQL
virt-customize: error: cannot use '--install' because no package manager
has been detected for this guest OS.
If this guest OS is a common one with ordinary package management then this
may have been caused by a failure of libguestfs inspection.
For OSes such as Windows that lack package management, this is not
possible. Try using one of the '--firstboot*' flags instead (described in
the manual).
Introduce and use a new inspect_mount_root function to mount all the
mountpoints of a root in the guest, replacing the same code doing that
in different tools.
inspect_mount_root_ro is inspect_mount_root with readonly mount option.
Support globbing in paths passed to --delete, telling glob to not
return directories with leading slash.
This re-adds back globbing for --delete in virt-sysprep, which was
available before the integration with common code from virt-customize.
For functions linked to virt tools, make sure the name of the function
actually matches the virt tool. Because of the history of moving
functions across tools, some names no longer matched.
For mllib, use `guestfs_int_mllib_' prefix.
For OCaml bindings, use `guestfs_int_ocaml_' prefix.
This commit is by no means complete. There are many other C functions
in other language bindings which could do with being more consistently
named.
There is no functional change, this is just refactoring.
Actually the OCaml compiler rewrites all printf functions at compile
time to a series of primitive string operations, so the use of sprintf
here doesn't really matter. Still, it's a bit tidier not to use
sprintf where it's not needed.
Also this commit contains some code reformatting.
This is just refactoring.
