NAME
rcS - variables that affect the behavior of boot scripts
DESCRIPTION
The /etc/default/rcS file contains variable settings in POSIX format:
VAR=VAL
Only one assignment is allowed per line. Comments (starting with '#') are also allowed.
OPTIONS
The following variables can be set.
TMPTIME
On boot the files in /tmp will be deleted if their modification time, file status time and access
time are all at least TMPTIME days ago. A value of 0 means that files are removed regardless of
age. If you don't want the system to clean /tmp then set TMPTIME to a negative value (e.g., -1)
or to the word infinite.
SULOGIN
Setting this to yes causes init to spawn a sulogin on the console early in the boot process. If
the administrator does not login then the sulogin session will time out after 30 seconds and the
boot process will continue.
DELAYLOGIN
Normally the system will not let non-root users log in until the boot process is complete and the
system has finished switching to the default runlevel (usually level 2). However, in theory it is
safe to log in a bit earlier, namely, as soon as inetd has started. Setting the variable to no
allows earlier login; setting the variable to yes prevents it.
Some details: The DELAYLOGIN variable controls whether or not the file
/var/lib/initscripts/nologin is created during the boot process and deleted at the end of it.
/etc/nologin is normally a symbolic link to the latter location, and the login(1) program refuses
to allow non-root logins so long as (the target of) /etc/nologin exists. If you set the variable
to no then it is advisable to ensure that /var/lib/initscripts/nologin does not exist.
UTC This is used to govern how the hardware real time clock is interpreted when it is read (e.g., at
boot time, for the purpose of setting the system clock) and when it is written (e.g., at
shutdown). If this option is set to no then the system clock is assumed to be set to local time.
If the option is set to yes then the system clock is assumed to be set to something approximating
Coordinated Universal Time (UTC). (POSIX systems keep a variant of UTC, without leap seconds.)
On contemporary Debian systems (although change has been requested at
http://bugs.debian.org/346342), if UTC is set to no then /usr/share/zoneinfo must be readable
early in the boot process. If you want to keep /usr on a separate filesystem then you must still
ensure that the target of /etc/localtime points to the correct zone information file for the time
zone of the time kept in your hardware real time clock.
VERBOSE
Setting this option to no (in lower case) will make the boot process a bit less verbose. Setting
this option to yes will make the boot process a bit more verbose.
FSCKFIX
When the root and all other file systems are checked, fsck is invoked with the -a option which
means "autorepair". If there are major inconsistencies then the fsck process will bail out. The
system will print a message asking the administrator to repair the file system manually and will
present a root shell prompt (actually a sulogin prompt) on the console. Setting this option to
yes causes the fsck commands to be run with the -y option instead of the -a option. This will
tell fsck always to repair the file systems without asking for permission.
NOTE
The EDITMOTD and RAMRUN variables are no longer used.
