Pardon this question, but how do I do this "mount --make-rprivate /"
in C? I've tried stracing mount:
mount("/dev/mapper/Debian-root", "/", "none", MS_REC|MS_PRIVATE,
"errors=remount-ro,discard") = 0
... but every combination of MS_REMOUNT MS_REC MS_PRIVATE I've tried
on / and /proc leaves me with a /proc in the main system that simply
doesn't have any pid dirs.
The program in question is newpid:
https://github.com/ChristophBerg/newpid/blob/master/newpid.c
... with an extra chunk before mount(proc):
if (mount ("", "/", "", MS_REC|MS_PRIVATE, NULL) != 0) {
perror ("mount /");
exit (1);
}
Am I supposed to parse the current mount flags etc from /proc/mounts
before doing that?
