No, this doesn't fix the path munging to use real_argv0.
"fix"?
Is something incorrect, or is it just that you'd prefer
to move the definition of real_argv0 "up"?
I see only two uses of argv[0] in main:
- path-related stuff *before* I change argv[0] and define real_argv0
if (getenv ("LIBGUESTFS_PATH") == NULL &&
argv[0] &&
(argv[0][0] != '/' || strstr (argv[0], "/.libs/lt-") != NULL))
guestfs_set_path (g, "appliance:" GUESTFS_DEFAULT_PATH);
- then, this code, afterwards, that I did change to use real_argv0:
strcpy (cmd, "a=`virt-inspector");
while (optind < argc) {
if (strlen (cmd) + strlen (argv[optind]) + strlen (real_argv0) + 60
...
sprintf (&cmd[strlen(cmd)], "` && %s $a", real_argv0);
If you'd prefer to move the definition of real_argv0 to precede
the former, let me know, and I'll move it and adjust.
However, note that that has no impact on correctness.
