Guest path resolution trimmed the trailing slash of a path under a
mount alias (/savedata0, /download0, /app0 and the others), so the host
saw "file" for "file/": unlink, remove, sceKernelUnlink and rename
removed or moved the file, open opened it, and chmod and access
succeeded on it. The same path outside an alias already failed with
ENOTDIR, because the host got the slash.
FreeBSD 11.4 rejects it in lookup() (sys/kern/vfs_lookup.c):
/*
* If we're processing a path with a trailing slash,
* check that the end result is a directory.
*/
if ((cnp->cn_flags & TRAILINGSLASH) && dp->v_type != VDIR) {
error = ENOTDIR;
goto bad2;
}
On Linux and macOS a path under an alias now keeps its trailing slash
on the host path, as paths outside an alias do, so the host fails with
ENOTDIR for a file and directories with a trailing slash still work.
Windows keeps the previous behaviour; TechnicalDebt records it.
