Hi!=0A=
=0A=
We ran into an issue with the nlplug-findfs netlink socket buffer size bein=
g too small when trying to boot Alpine 3.17 on an enterprise server with a =
lot of devices. The size of that buffer is currently 1MiB. I created a PR t=
o make the size of that buffer configurable with a kernel parameter here:=
=0A=

https://gitlab.alpinelinux.org/alpine/mkinitfs/-/merge_requests/116=0A=
=0A=
I'm wondering if we should also consider increasing the default size of tha=
t buffer? Perhaps to 5MiB (fwiw, I've confirmed that this is big enough on =
our HW). I suppose that some users who run on very resource-constrained har=
dware might have objections, but 5MiB seems like it would probably be ok ev=
en in those cases?=0A=

Thanks,=0A=
