** Description changed:
+ [Impact]
+ systemd-systemctl will fail to set kernel.pid_max, leading to a degraded boot.
+
+ [Fix]
+ Set CONFIG_BASE_FULL=y, CONFIG_BASE_SMALL=0.
+
+ [Test case]
+ Write 419304 to /proc/sys/kernel/pid_max.
+
+ [Potential regression]
+ Boot time may be affected.
+
+
There is no other effect of disabling CONFIG_BASE_FULL save for changing
CONFIG_BASE_SMALL.
CONFIG_BASE_SMALL won't have much effect save for other memory savings
that really would be able to reduce some runtime performance. As for
boot time, changing this setting should not be expected to cause

You received this bug notification because
Linux KVM is meant for VM guests and probably therefore was set to
CONFIG_BASE_SMALL=1.
The discussion "if this makes sense or not" is up to the kernel team but it
seems this bug has got no attention by them yet :-/.
I was quickly assessing the case and found:
- Linux-generic is on
Obviously
- linux-kvm in B/F/G/H was all the time set to CONFIG_BASE_SMALL=0
was some copy-pasta and should be
- linux-kvm in X/B/F/G/H was all the time set to CONFIG_BASE_SMALL=1

This is causing LXD VMs (Focal, possibly others) to boot in "degraded"
state, see [1]. The underlying cause is:
root@paride-f-delme:~# systemctl status systemd-sysctl.service
● systemd-sysctl.service - Apply Kernel Variables
Loaded: loaded (/lib/systemd/system/systemd-sysctl.service; static;
Status changed to 'Confirmed' because the bug affects multiple users.
