Hi, * Salvatore Bonaccorso [Fri Nov 25, 2022 at 02:07:25PM +0100]:
sysctl settings (e.g. /etc/sysctl.conf and others) are normally loaded
once at boot. If the module that implements some settings is no yet
loaded, those settings don't get applied.
Various NFS modules support various sysctl settings. If they are loaded
after boot, they miss out.
Add a new udev rule configuration to udev/rules.d/60-nfs.rules to apply
the relevant settings when the module is loaded.
Placing it in the systemd directory similarly as the coice for the
original commit afc7132dfb21 ("systemd: Apply all sysctl settings when
NFS-related modules are loaded").[...]

[...] Thanks for taking care of this problem, Salvatore! AFAICT even latest busybox's sysctl does not support the `--pattern` option yet: | sysctl: unrecognized option '--pattern' | BusyBox v1.35.0 (Debian 1:1.35.0-4) multi-call binary. | [....] So any initramfs that uses busybox and its sysctl (like in Debian) and trying to apply above udev rules might fail? regards -mika-
