Subject: [PATCH 127/135] agetty: fix /etc/os-release parsing
|
|
|
5f5089 |
|
|
|
5f5089 |
For example /etc/os-release:
|
|
|
5f5089 |
|
|
|
5f5089 |
VERSION="26 (Twenty Six)"
|
|
|
5f5089 |
VERSION_ID=26
|
|
|
5f5089 |
|
|
|
5f5089 |
agetty for \S{VERSION} returns
|
|
|
5f5089 |
|
|
|
5f5089 |
_ID=26
|
|
|
5f5089 |
|
|
|
5f5089 |
because the parser does nor check for '=' after variable name.
