This isn't really a Git bug; it's more of a difference with how the
MSYS2 runtime shipped with Git for Windows works. Note that the Git
project doesn't ship binaries or any software other than Git itself; Git
for Windows is the distributor of that and can be reached at
https://github.com/git-for-windows/git.
However, the reason you're seeing this is because most programs on
Windows don't accept the Unix-style paths that MSYS2 and Git Bash
provide, so to placate them, Git Bash converts paths that start with a
slash into Windows-style paths. The root directory for Git Bash is the
Git installation directory, so when you write `/usr/share/nginx/html`,
Git Bash turns that into `C:\Program Files\Git\usr\share\nginx\html`.
The `$PWD` is not necessarily related here, although it may undergo the
same expansion.
If you don't want that behaviour, then you can use a double slash (e.g.,
`//usr/share/nginx/html`), or you can set `MSYS_NO_PATHCONV=1`, like so:
MSYS_NO_PATHCONV=1podman run -p 8081:80 -v $PWD:/usr/share/nginx/html nginx
Note that you probably _do_ want `$PWD` to undergo expansion with MSYS,
though, so you may want to do this instead (untested):
MSYS_NO_PATHCONV=1podman run -p 8081:80 -v "$(cygpath -w "$PWD"):/usr/share/nginx/html" nginx
If you have more questions about this, I'd reach out to the Git for
Windows folks.
