- use _ throw-away variable to get rid of a shellcheck warning
- remove tests for /etc/hostname and just try to read it
- drop reference to bash HOSTNAME variable.
- make source of host name more accurate

(This is analogous to the rc_stringlist change.)
This gives a hint to the compiler that allocations (return values)
from this function should be paired with a corresponding dealloc/free
function.

This gives a hint to the compiler that allocations (return values)
from this function should be paired with a corresponding dealloc/free
function
In this case, it means that every rc_stringlist that rc_stringlist_new()
returns should eventually be freed by calling rc_stringlist_free(ptr)
where ptr is the relevant rc_stringlist.
We have to add a test for this into the build system
because only GCC supports this for now. In future, we might
be able to use meson's has_function_attribute (it does support
'malloc', just not AFAICT 'malloc with arguments').

'services' is still referenced by the list
which gets returned. We can't free it.
Thanks to GCC 11's -fanalyzer.

The value of ${seed_dir} may have spaces in it, making the current
argument string building method unsafe. Instead, use positional
parameters to pass these arguments safely.
There have been a number of subtle improvements and cleanups to seedrng,
including using openat and locking the directory fd instead of a
separate lock file. Also various stylistic cleanups.
This fixes#519.

* rewrite tests to work with meson
This ports our tests to meson and makes them able to be run in parallel.
* add tests to ci
* rewrite test/check-trailing-newlines in bash
This test was using a GNU sed command which does not work on Alpine Linux.
- drop old build system
- move shared include and source files to common directory
- drop "rc-" prefix from shared include and source files
- move executable-specific code to individual directories under src
- adjust top-level .gitignore file for new build system
This closes#489.
The RNG can't actually be seeded from a shell script, due to the
reliance on ioctls. For this reason, the seedrng project provides a
basic script meant to be copy and pasted into projects like OpenRC and
tweaked as needed: https://git.zx2c4.com/seedrng/about/
This commit imports it into OpenRC and wires up /etc/init.d/urandom to
call it. It shouldn't be called by other things on the system, so it
lives in rc_sbindir.
Closes#506.
Closes#507.

This add No New Privs flag for start-stop-daemon and supervise-daemon
by adding --no-new-privs flag. As a result, the user set the No New
Privs flag for the program should run with.
