non-deterministic test failure of the 'PleaseRun::CLI when setting --install-prefix should write files there'

[Apteryks]

Hi,

About one out of 10 times, I get the following test failure using the latest release of pleaserun (0.0.32):

starting phase `check'
{:WRIT=>false}
{:timestamp=>"2023-03-18T01:38:22.243480+0000", :message=>"Writing file", :destination=>"/tmp/guix-build-ruby-pleaserun-0.0.32.drv-0/studtmp-f959f7fcd57724b44e243877895a45e8f71e5e0db3d2458519598a78653b/etc/init.d/"}

Pending: (Failures listed here are expected and do not affect your suite's status)

  1) PleaseRun::Platform::SYSV deployment cannot write to /etc/init.d, so there's no deployment test to do. To run these tests, you'll need to run this as root, and preferrably in a vm or other temporary system
     # Not yet implemented
     # ./spec/pleaserun/platform/sysv_spec.rb:13

I'll disable the test in the meantime for the Guix package I'm preparing.

Thank you!

Oh fun! Good find :)

this does look like a bug in the test suite, but I have not investigated further
