Description Steve Traylen 2022-02-01 09:57:39 UTC

Description of problem:

The recently released systemd on CentOS Stream 8 tried to re-enable
ping functionality with a systemd sysctl.d entry.

Unfortunately this entry contains a `-` as prefix which is I expect only
valid on newer systemds.

[root@cs8]# grep '^-' /usr/lib/sysctl.d/*
/usr/lib/sysctl.d/50-default.conf:-net.ipv4.ping_group_range = 0 2147483647

Version-Release number of selected component (if applicable):
systemd-239-56.el8.x86_64

How reproducible:

Every time

Steps to Reproduce:
1. Install systemd-239-56.el8.x86_64
2. dnf -y reinstall systemd


Actual results:

The systemd rpm scriptlets output

 Couldn't write '0 2147483647' to '-net/ipv4/ping_group_range', ignoring: No such file or directory

and the intention did not happen:

# cat /proc/sys/net/ipv4/ping_group_range 
1       0

has not been updated.


Expected results:

Should have updated "/proc/sys/net/ipv4/ping_group_range"

Additional info:

I would presume just taking the `-` out should be good.
