ca8e66a8b0 Make init handle reboots
Move the responsibility for rebooting the system from the
reboot command to init. Init is in a better position to take
actions to bring the system down cleanly, including making sure
filesystems are mounted read-only.

The only UIDs which can perform an init triggered reboot are
root, system, and shell.

Modify the reboot command so that it calls into init to perform
the reboot. The reboot command no longer requires CAP_SYS_BOOT.

Remove the -n reboot option and code which supports it.  Anyone needing
to do an unclean shutdown can just do a 'echo c > /proc/sysrq-trigger'.

Modify adb so that it calls into init to perform a shutdown.

0e23fee505 Change setsebool syntax to be consistent with other init built-ins.
Change setsebool syntax from name=value to name value.
This is to make it consistent with setprop and similar commands.
Update both the init built-in command and the toolbox command
for consistency.

5c8574b512 init: Fix mkdir command when using ISUID or ISGID bit
On first boot, the directory is created with root:root ownership and
then chowned. chown clears the ISUID and ISGID bits, so we need to chmod
the directory again after chown.

ef3f7fa32b Merge "Set the SELinux security label on new directories." 2012-08-08 13:42:20 -07:00
Stephen Smalley
e096e36e50 Set the SELinux security label on new directories.
Automatically set the SELinux security label on directories created
by init.rc.  This avoids the need to separately call restorecon on
each such directory from the init.rc file.  Also restorecon /dev
and /dev/socket after initial policy load so that they are labeled
correctly before any other dev nodes or sockets are created.

96d0a4dda8 Extend and document the "wait" command
The wait command was currently implemented but
undocumented and only used internally. This change
adds a second option toi (optionally) override the default
timeout of 5 seconds.

The wait command can be used to wait for a file to appear
during the boot process, for example a disk or other device,
and is a better alternative than an unconditional sleep.

0e9dd90ac3 Change init to use libfs_mgr to mount filesystems.
The new fs_mgr library moves much of the knowledge of what filesystems
to mount into a new fstab.<device> file, and just calls one function to
mount all the filesystems.

    write /data/foo $$hello

c5c51033c8 Load the persistent properties after decrypting the /data partition
Fix for bug 3415286.  The persistent properties are normally read early
in the boot process after /data is mounted.  However, for an encrypted
system, at that point /data is a tmpfs ramdisk.  This change adds a new
command to init (load_persist_props) to read the persistent properties,
and adds an action to init.rc to load the persistent properties.  This
action is triggered by setting a property in vold, but that's in a
different CL.
