[Pkg-sysvinit-devel] Bug#519520: No concurrency for .sh scripts

[Cortese, Matteo]

Package: sysv-rc
Version: 2.86.ds1-61

Init scripts with trailing .sh are treated differently than other
scripts, which is explained in detail in bug #339955.
The current solution gives the choice to the user of setting the "sh"
variable to either:
    "." if he wants .sh scripts to be sourced,
    "sh" if he wants .sh scripts to be treated like the others.

In the latter case, however, .sh scripts are NOT treated like the others
when $CONCURRENCY=shell. A .sh script is executed this way:

    $debug sh "$script" $action

while a non-.sh script is executed this other way:

    $debug "$script" $action &
    backgrounded=1

As a result, .sh scripts will never be run in parallel, even in
runlevels other than S (for which the Policy issue does not apply).
