Bug 25212

Maybe this should be done differently nowadays?

Assigning to the base system maintainers.

Sorry in step #2 I miscopied the order, I really typed (just to clarify that it's not a mistake on my part) :

# echo "vm.swappiness=10" >> /etc/sysctl.conf

I don't find info about this, in my system i have a /etc/sysctl.conf.rpmsave , this files are usually created when some change in the format of a file or other changes.

So maybe /etc/sysctl.conf is deprecated and now have to create files under /etc/sysctl.d/

Keep the naming of the file 51-alt-sysrq.conf and create yours like  

echo "vm.swappiness=10" > /etc/sysctl.d/50-swappiness.conf

Remove the simlink to /etc/sysctl.conf in /etc/sysctl.d to test if this works

/etc/sysctl.conf.rpmsave is the result of upgrade from Mga6 to Mga7, normal.

But Mga7 creates a /etc/sysctl.conf that contains (verified with a fresh install under vm) :

net.ipv4.icmp_ignore_bogus_error_responses=1
net.ipv4.icmp_echo_ignore_broadcasts=0
net.ipv4.icmp_echo_ignore_all=0
net.ipv4.conf.all.rp_filter=1
net.ipv4.conf.all.log_martians=1

However, this file is not read when the machine is started.

I agree that its place may now be under /etc/syctl.d/ (I'm not a sysctl nor a kernel specialist) but in this case Mga7 (or sysctl) should not create /etc/sysctl.conf and put instructions there that will not be read.

Concerning your workaround method it works since any file contained in /etc/sysctl.d/ is read.

But I prefer naming this file /etc/sysctl.d/50-sysctl.conf (not only swappiness parameters could be added)
However, this bug needs to be fixed. (In the meantime, shouldn't this be added to the errata?)

This bug is resolved before. 

- Go to dolphin as root. (In konsole as root: dolphin)
- Go to /etc/sysctl.d
- Create new archive "99-sysctl.conf".
- Write in the archive: vm.swappiness=10 (The value needed)
- Reboot the computer.
- Confirm the value in konsole as root with: cat /proc/sys/vm/swappiness

Regards!!

It is msec that should be updated to write to /etc/sysctl.d/51-drakx.conf instead of /etc/sysctl.conf

that way it will match with atleast drakx-net uses...

Like this I think:

I don't understand : you did this commit, so is it ready to release a 2.8 msec version?

I committed it as "I think its correct", but still need to check if other drakx bits follows... I know drakx-net uses that file, but I havent checked the rest of the drakx tools yet.

2.8 has been pushed, including the commit of Thomas.
It is now OK?

Advisory
===================
msec used /etc/sysctl.conf file, which is no more read by systemd.
With the modification, it uses now /etc/sysctl.d/51-drakx.conf such that all directives given in this file are taken.
===================

mga7, x86_64

Before update:

# sysctl vm.swappiness
vm.swappiness = 60
# echo "vm.swappiness=10" > /etc/sysctl.conf
# sysctl vm.swappiness
vm.swappiness = 60

Reboot
# sysctl vm.swappiness
vm.swappiness = 60

Updated msec.

# echo "vm.swappiness=10" > /etc/sysctl.d/51-drakx.conf
That file was initially empty but the original file seems to be there still.
# sysctl vm.swappiness
vm.swappiness = 60
# ll /etc/sysctl.conf
-rw-r--r-- 1 root root 196 Jun  9 18:01 /etc/sysctl.conf
# less /etc/sysctl.d/51-drakx.conf
...
vm.swappiness=10
/etc/sysctl.d/51-drakx.conf (END)

sysctl.conf could be removed perhaps.
After another reboot sysctrl found the new value.
# sysctl vm.swappiness
vm.swappiness = 10
# cat /proc/sys/vm/swappiness
10
