|
|
# 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).
|
|
ulimit -Hn 8192

.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.
