Subject: kbuild: deb-pkg: Remove blank first line from maint scripts
X-Git-Url: https://git.dujemihanovic.xyz/?a=commitdiff_plain;h=82cb44308951ad4ce7a8500b9e025d27d7fb3526;p=linux.git

kbuild: deb-pkg: Remove blank first line from maint scripts

The blank line causes execve() to fail:

  # strace ./postinst
  execve("./postinst", ...) = -1 ENOEXEC (Exec format error)
  strace: exec: Exec format error
  +++ exited with 1 +++

However running the scripts via shell does work (at least with bash)
because the shell attempts to execute the file as a shell script when
execve() fails.
