Bug#1051328: grub-common: wrong-path-for-interpreter /usr/bin/sh != /bin/sh [etc/grub.d/25_bli]

[Axel Beckert]

Package: grub-common
File: /etc/grub.d/25_bli
Version: 2.12~rc1-7
Version: 2.12~rc1-9
Severity: serious

For some reason, possibly usrmerge-triggered, since 2.12~rc1-7
/etc/grub.d/25_bli sports the following non-standard shebang line:

  #!/usr/bin/sh

as lintian also reports:

  → lintian grub-common_2.12\~rc1-9_amd64.deb
  E: grub-common: wrong-path-for-interpreter /usr/bin/sh != /bin/sh [etc/grub.d/25_bli]

Interestingly only this single file seems to be affected.
