As in 2a5fcfae02
and in 3e67e5c992
using /usr/bin/env allows bash to be looked up in PATH
rather than being hard-coded.
As with the previous changes the same arguments apply
- distributions have scripts to rewrite shebangs on installation and
they know what locations to rely on.
- For tests/compilation we should rather rely on the user to have setup
there PATH correctly.
In particular this makes testing from git easier on NixOS where do not provide
/bin/bash to improve compose-ability.
TEST-41 verifies that the StartLimitBurst property will correctly
limit the number of unit restarts, but the test currently doesn't
adjust the StartLimitIntervalSec which defaults to 10 seconds.
On Ubuntu CI, running under un-accelerated qemu, it can take more than
10 seconds to perform all 3 restarts, which avoids the burst limit,
and fails the test.
Instead, specify a long StartLimitIntervalSec in the test, so we can
be sure to correctly test StartLimitBurst even on slow testbeds.
Fixes#13794.
