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 /run/nologin is created during the boot process and
deleted at the end of it. The login(1) program refuses to allow
non-root logins so long as /run/nologin exists. If you set the
variable to no then it is advisable to ensure that /run/nologin
does not exist.
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, RAMRUN and UTC variables are no longer used. The UTC
setting is replaced by the UTC or LOCAL setting in /etc/adjtime, and
should have been migrated automatically. See hwclock(5) and hwclock(8)
for further details on configuring the system clock.
