[bug #13832] Cannot execute user menu command if temporary directory is in filesystem mounted with noexec option

[Leonard den Ottolander <savannah-bounces gnu org>]

Follow-up Comment #5, bug #13832 (project mc):

Before committing this patch I'd like to see it extended in either of the
following ways first:

a) Test for mount options of $MC_TMPDIR and concatenate "/bin/sh " only when
necessary.
b) Extend shell_execute(), do_execute() to pass the error generated by
my_system on failure. Execute the command plainly and in case of an error
caused by the mount options execute it once again with a concatenated shell.
c) Extend to pass error as in b). Test on init and set a parameter
(need_shell) so we don't have to do this test on every invokation of
shell_execute(). In case of failure because the mount option changed during
the session reset the parameter need_shell to new value and retry.

I would prefer the last option.
