Subject: vcs-snapshot.eclass: set -o (--no-same-owner) when unpacking, bug #645182
X-Git-Url: http://git.tremily.us/gitweb.cgi?a=commitdiff_plain;h=a10a1bf072ae90445fb6d238659a799d3bf55375;p=gentoo.git

vcs-snapshot.eclass: set -o (--no-same-owner) when unpacking, bug #645182

Fixes build failures in unprivileged containers like bug #645182:
  Package:    dev-python/pycparser-2.14
  >>> Unpacking source...
  tar: CHANGES: Cannot change ownership to uid 1000, gid 1000: Invalid argument

In such containers uid=0 can't really change file ownership.

Closes: https://bugs.gentoo.org/645182
