pub fn current_exe_resolved() -> Result<PathBuf>Expand description
Resolve the path of the currently-running executable, robust to the Linux
kernel’s (deleted) marker.
When a running binary is replaced in place — e.g. cargo install slancha-wire unlinks and recreates ~/.cargo/bin/wire while wire upgrade
is still running — the kernel appends a literal (deleted) suffix to
/proc/self/exe. That suffix marks the unlinked inode; it is NOT part of
the path. std::env::current_exe surfaces it verbatim, and writing it
into a systemd ExecStart= / launchd program path corrupts the unit
(error: unrecognized subcommand '(deleted)', the unit then flaps forever).
This strips a trailing (deleted) so callers get the real install path,
which the in-place replacement has already recreated on disk. Issues #274,
#276.
