Hello
i have observed a to my (limited) understanding a strange behavior regarding
limits settings. I would like some hint if i am doing s.th. wrong or if i
encountered a bug.
i have the following:
----------------------------------------------------
/etc/security/limits.conf
----------------------------------------------------
* - nproc 512
root soft nproc 1024
root hard nproc 2048
* - nofile 8192
root - nofile 16383
----------------------------------------------------
limits.conf(5):
NOTE: group and wildcard limits are not applied to the root
user. To set a limit for the root user, this field must
contain the literal username root.
With the settings above applied when i log in on a vt as root i get the
follwoing limits for user root:
root on vt:
# ulimit -Hu
2048
# ulimit -Hn
16383
# ulimit -Su
1024
# ulimit -Sn
16383
^- These are excepted results.
Now when i log into kde and start konsole or a xterm and 'su -' i get the
following:
root in kde:
# ulimit -Sn
8192
# ulimit -Hn
8192
# ulimit -Su
512
# ulimit -Hu
512
su(1):
-, -l, --login
Provide an environment similar to what the user would
expect had the user logged in directly.
As you can see in this case the limits defined for a ordinary user are applied
for root. IMO this is a bug as it breaks documented behavior.
Should this be reported or am i missing s.th.?
