NAMErcS - variables that affect the behavior of boot scripts
DESCRIPTIONThe /etc/default/rcS file contains variable settings in POSIX format:
Only one assignment is allowed per line.
Comments (starting with '#') are also allowed.
OPTIONSThe following variables can be set.
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.
- Setting this to yescauses 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.
- 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 inetdhas 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.
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.
When the root and all other file systems are checked,
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.
