Subject: [PATCH] man/os-release: add a note about repeating entries
|
||
|
|
|
||
|
|
We didn't actually say that keys should not be repeated. At least the
|
||
|
|
examples in docs (both python and shell) would do that, and any simple
|
||
|
|
parser that builds a dictionary would most likely behave the same way.
|
||
|
|
But let's document this expectation, but also say how to deal with malformed
|
||
|
|
files.
|
||
|
|
|
||
|
|
