[pkg-cryptsetup-devel] Bug#524485: [cryptsetup] it's because piped `while-read' loop starts subshell

[Rex Tsai]

Package: cryptsetup
Version: 2:1.0.6+20090405.svn49-1

  I encountered same issue. After a quick check, I found the problem is
because cryptdisks_start use a while-read loop, which starts a subshell.

  Enclosed please find the patch for this problem.
