Subject: tree-wide: get rid of backslashes in file names
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=d04fbcf956a7454b9626c668df5208ca6b5cf385;p=thirdparty%2Fsystemd.git

tree-wide: get rid of backslashes in file names

File names containing backslashes cannot be checked out on Windows,
are not handled properly by build systems such as buck, and are awkward
to work with in general, so store the \x2d slice units under sanitized
file names, and rename them to the real unit name on install via a new
optional "name" key in the units list.

The fuzz-unit-file corpus sample is renamed as well; its file name is
not meaningful to the fuzzer, and dropping the backslash means it is no
longer skipped by the meson workaround for
https://github.com/mesonbuild/meson/issues/1564, so it runs as a
regression test again.
