Hi Hans,
the problem with this is, that we get some lvm properties, which look like this:
{ 'LVM_SOMETHING' : 'abc LVM_SOMETHING=def LVM_SOMETHING=xyz' }
With regular split(), I would have to go over the list, and remove the LVM_SOMETHING= parts from [1:] items,
re.split() does this for me.
Erm, no:

Type "help", "copyright", "credits" or "license" for more information.
>>> a = "foo bar=foo2 bar=foo3"
>>> a.split(" bar=")
['foo', 'foo2', 'foo3']

But you're right about the re special chars in name, that would break everything.
I don't know if there are some special chars allowed in the udev properties keys, are they?
If yes, I can do it with, .find(), .split(), .replace(), do you think it will be a better solution?
Yes as then you don't have to worry about re special chars in the key, and as shown above,
regular split will handle this just fine.
Regards,
Hans

Hi,
Why are you using a re.split and not just a regular split,
also what happens if name has any re special chars in it,
is there a re escape function you can use?
Regards,
Hans

Some of the values which are returned by udev are strings,
which contain more values for the same key.
The string format is "val1 key=val2 key=val3 ...".
This fix makes sure we split this string into a list of values.
