About init

I know if a parent process exits before its child, the last one becomes orphan for a while and then is added to the children of Init process. I'd like to know deeper 1 how the orphan becomes init process, 2 how init knows that from a some point on it has another child. Thank you in advance.

How to I change init levels after typing init 1

Dear all, I typed in init 1 on my redhat box as root and according to wikipedia (http://en.wikipedia.org/wiki/Runlevel): 1 Single-User Mode Does not configure network interfaces, start daemons, or allow non-root logins So now I can't connect back to it. How do I change the init back to 3?...

systemd-fsck

SYSTEMD-FSCK@.SERVICE(8)				       systemd-fsck@.service					  SYSTEMD-FSCK@.SERVICE(8)

NAME

       systemd-fsck@.service, systemd-fsck-root.service, systemd-fsck - File system checker logic

SYNOPSIS

       systemd-fsck@.service

       systemd-fsck-root.service

       /lib/systemd/systemd-fsck

DESCRIPTION

       systemd-fsck@.service and systemd-fsck-root.service are services responsible for file system checks. They are instantiated for each device
       that is configured for file system checking.  systemd-fsck-root.service is responsible for file system checks on the root file system, but
       only if the root filesystem was not checked in the initramfs.  systemd-fsck@.service is used for all other file systems and for the root
       file system in the initramfs.

       These services are started at boot if passno in /etc/fstab for the file system is set to a value greater than zero. The file system check
       for root is performed before the other file systems. Other file systems may be checked in parallel, except when they are on the same
       rotating disk.

       systemd-fsck does not know any details about specific filesystems, and simply executes file system checkers specific to each filesystem
       type (/sbin/fsck.*). This helper will decide if the filesystem should actually be checked based on the time since last check, number of
       mounts, unclean unmount, etc.

       If a file system check fails for a service without nofail, emergency mode is activated, by isolating to emergency.target.

KERNEL COMMAND LINE

       systemd-fsck understands these kernel command line parameters:

       fsck.mode=
	   One of "auto", "force", "skip". Controls the mode of operation. The default is "auto", and ensures that file system checks are done
	   when the file system checker deems them necessary.  "force" unconditionally results in full file system checks.  "skip" skips any file
	   system checks.

       fsck.repair=
	   One of "preen", "yes", "no". Controls the mode of operation. The default is "preen", and will automatically repair problems that can be
	   safely fixed.  "yes" will answer yes to all questions by fsck and "no" will answer no to all questions.
