This makes the line parsing a lot more robust (and easier to read).
Code supplied by @dhozac, thanks!
Remove re import because this is not used anywhere.
When trying to perform enabled=yes followed by enabled=no
against FreeBSD the module would die with the following error:
TypeError: sub() takes at most 4 arguments (5 given)
The target FreeBSD client (8.2) is running python 2.6.6. It seems the
extra 'flags' argument was added to re.sub() in 2.7.
In fixing this issue I have attempted to create a general atomic method
for modifying a rc.conf file. Hopefully this will make it easier to add
other rc based platorms. The strip/split magic was inspired by the user
module.
* Basically the moving parts from the original service module arranged in
subclasses.
* General structure and helper methods comes from the user module.
* Less forgiving to unsupported platforms: it requires a subclass per platform.
(This makes it easier to work on one platform without having to think about.
what other platform might be affected in unexpected ways).
* Now has basic OpenBSD support.
* Solaris support needs to be added.
Thanks to @dhozac for general advice and Linux testing.
Thanks to @bcoca for clearing up some FreeBSD questions.
I added all known virtualization types from the virt-what project. However, the few virt types that rely on cpuid information have not been implemented lacking native python cpuid access. (hyperv)
Without this fix, generating documentation results in:
