looking at a simple program:
int main()
{
if (fork()) return 0;
printf("pid = %i\n", getpid());
while (1) sleep(3600);
}
and where my / and /var/tmp are on the same partition:
# gcc test.c -o /usr/sbin/MOO
# /usr/sbin/MOO
pid = 17144
# readlink /proc/17144/exe
/usr/sbin/MOO
# gcc test.c -o /var/tmp/MOO
# mv /var/tmp/MOO /usr/sbin/MOO
# readlink /proc/17144/exe
/var/tmp/MOO (deleted)
i feel like the new exe link should actually read:
/usr/sbin/MOO (deleted)
otherwise people can easily get confused as they think their daemon
was started in /var/tmp/ and their machine was compromised
