Subject: Set -u in live-snapshot only in debug mode.
X-Git-Tag: debian/2.0.15-1~427
X-Git-Url: http://git.grml.org/?a=commitdiff_plain;h=31d899e6c14d658569d70f6fe62a0fbe1f750fa9;hp=e44b1421fb3fcfac5097f946a7b40863dd60a364;p=live-boot-grml.git

Set -u in live-snapshot only in debug mode.

* Although is really fine to have checks for unboud variables, this
  limits also included code, where unbound variables could be used as
  feature. Set LIVE_SNAPSHOT_CHECK_UNBOUND to have it on again in your
  test runs.
