Subject: [PATCH] grml-chroot: mount /dev/pts as devpts inside chroot
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Fixes:

| E: Can not write log (Is /dev/pts mounted?) - posix_openpt (2: No such file or directory)

Thanks: András Korn for proposing the --rbind/--recursive approach
