Editing sysctl.conf Petalinux

[skaat27]

 Hi,

I want to edit the sysctl.conf file and change few variables (like buffer sizes). I am using petalinux and was wondering how to edit that file (I couldnt find it anywhere). I can boot petalinux and then run sysctl command, but i want to edit the sysctl.conf permanently at boot.

Regards,

Karthik

Did you ever figure out how to do this?

Hi

See if this post helps you, but this is to change /etc/syslog-startup.conf. Same should be applicable to edit /etc/sysctl.conf

I am using Petalinux 2019.2. There is no recipes-core directory under project-spec/meta-user.

How can I modify /etc/sysctl.conf in this case?

Thanks,

Anybody had any success in this?

I tried to apply changes to procps recipe (petalinux yocto 2018.1), as I found that it is the recipe for generating the sysctl.conf in /etc.

Created a .bbappend for the procps receipe with my changes in sysctl.conf.

Surprisingly my rootfs doesn't has the /etc/sysctl.conf or /etc/sysctl.d files/folders.

I tried removing the bbappend, but still the /etc/sysctl.conf is not getting deployed in rootfs.

Any help, what may I be missing.
