The reason is that ulimit(), by definition, works only on the current process.
Plus, it would be really fun to have to implement it working on all existing processes for a user. To do that /etc/profile or the user's profile is the place to enforce limits.

Hi, All
I need to increase the ulimit value permanently without changing /etc/system file. i.e nofiles descriptor.
For all NIS Users logging in.
I know the command to do this:
# ulimit -Sn 4096
This change is temporary.
So, I went on adding this command in the /etc/profile.

aa-genprof
AA-GENPROF(8) AppArmor AA-GENPROF(8)
NAME
aa-genprof - profile generation utility for AppArmor
SYNOPSIS
aa-genprof <executable> [-d /path/to/profiles]
OPTIONS
-d --dir /path/to/profiles
Specifies where to look for the AppArmor security profile set.
Defaults to /etc/apparmor.d.
DESCRIPTION
When running aa-genprof, you must specify a program to profile. If the specified program is not a fully-qualified path, aa-genprof will
search $PATH in order to find the program.
If a profile does not exist for the program, aa-genprof will create one using aa-autodep(1).
Genprof will then:
- set the profile to complain mode
- write a mark to the system log
- instruct the user to start the application to
be profiled in another window and exercise its functionality
It then presents the user with two options, (S)can system log for entries to add to profile and (F)inish.
If the user selects (S)can or hits return, aa-genprof will parse the complain mode logs and iterate through generated violations using
aa-logprof(1).
After the user finishes selecting profile entries based on violations that were detected during the program execution, aa-genprof will
reload the updated profiles in complain mode and again prompt the user for (S)can and (D)one. This cycle can then be repeated as necessary
until all application functionality has been exercised without generating access violations.
When the user eventually hits (F)inish, aa-genprof will set the main profile, and any other profiles that were generated, into enforce mode
and exit.
