Would it be reasonable for your patch to return EROFS rather than
EACCES?
man 2 open:
int open(const char *pathname, int flags, mode_t mode);
EROFS pathname refers to a file on a read-only file system and write
access was requested.
EACCES The requested access to the file is not allowed, or search perâ
mission is denied for one of the directories in the path prefix
of pathname, or the file did not exist yet and write access to
the parent directory is not allowed. (See also path_resoluâ
tion(7).)
