Section: Debian Administrator's Manual (5)
Updated: 21 May 2012
The /etc/default/rcS file contains variable settings in POSIX format:
Only one assignment is allowed per line. Comments (starting with '#') are also allowed.
The following variables can be set.
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.
The EDITMOTD, RAMRUN and UTC variables are no longer used. The RAMLOCK, RAMSHM and RAMTMP variables have been moved to /etc/default/tmpfs; RAMSHM and RAMTMP settings in rcS are used (if set) for backward compatibility, but will be overridden by settings enabled in /etc/default/tmpfs. See tmpfs?(5) for further details. The settings are not automatically migrated to /etc/default/tmpfs. Please update /etc/default/tmpfs appropriately. 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.
