# initscript Executed by init(8) for every program it

|
# wants to spawn like this:

|

#
|

|
# /bin/sh /etc/initscript <id> <level> <action> <process>
|
||
|
|
#
|
||
|
|
|
||
|
|
# Set umask to safe level, and enable core dumps.

# Increase the hard file descriptor limit for all processes
|
||
|
|
# to 8192. The soft limit is still 1024, but any unprivileged
|
||
|
|
# process can increase its soft limit up to the hard limit
|
||
|
|
# with "ulimit -Sn xxx" (needs a 2.2.13 or later Linux kernel).

.SH NOTES
|
||
|
|
This script is not meant as startup script for daemons or somesuch.
|
||
|
|
It has nothing to do with a \fIrc.local\fP style script. It's just
|
||
|
|
a handler for things executed from \fB/etc/inittab\fP. Experimenting
|
||
|
|
with this can make your system un(re)bootable.
