With init, skipping a scheduled fsck during boot was easy, you just pressed
Ctrl+c, it was obvious! Today I was late for an online conference. I got
home, turned on my computer, and systemd decided it was time to run fsck on my
1TB hard drive. Ok, I just skip it, right? Well, Ctrl+c does not work, ESC
does not work, nothing seems to work. I Googled for an answer on my phone but
nothing. So, is there a mysterious set of commands they came up with to skip an
fsck or is it yet another flaw?

Увидел следующую замену systemd:

#define _XOPEN_SOURCE 700
#include <signal.h>
#include <unistd.h>

int main()
{
    sigset_t set;
    int status;

    if (getpid() != 1) return 1;

    sigfillset(&set);
    sigprocmask(SIG_BLOCK, &set, 0);

    if (fork()) for (;;) wait(&status);

    sigprocmask(SIG_UNBLOCK, &set, 0);

    setsid();
    setpgid(0, 0);
    return execve("/etc/rc", (char *[]){ "rc", 0 }, (char *[]){ 0 });
}

Какие подводные камни?
