Subject: [PATCH] Fix faulty runc version commit scrape
|
|
|
|
This commit replaces faulty logic to determine the runc version commit hash.
|
|
|
|
The original logic takes the second line of the output of "runc --version" and
|
|
does not work if there are a different number of lines printed from the command
|
|
than expected. The buildroot version of runc outputs two lines instead of the
|
|
expected three, causing the error:
|
|
|
|
unknown output format: runc version commit: ...
|
|
|
|
This patch replaces this logic with a simple scan of the "runc --version"
|
|
output, searching for the "runc version commit" prefixed line.
