Subject: tar: avoid assumptions about root access and chmod -w in test cases
X-Git-Url: https://git.dogcows.com/gitweb?a=commitdiff_plain;h=0adf4027f5859235c2e3bb61b564c95ec018fe61;p=chaz%2Ftar

tar: avoid assumptions about root access and chmod -w in test cases

* tests/extrac07.at, tests/extrac09.at, tests/listed03.at: Use
AT_UNPRIVILEGED_PREREQ, since this test requires non-root
privileges.
* tests/extrac07.at: Don't use "chmod -w", as POSIX says it's not
portable to start a chmod permissions-list with "-" as it may be
confused with an option.  Use "chmod a-w" instead.
