The warning described in the title is displayed when running mix firmware on mac. This is caused by the mac file system's case-insensitive handling of file names.

For example, the netfilter kernel modules include the following, which are distinguished as separate files in linux.

/lib/modules/5.10.83/kernel/net/netfilter/xt_DSCP.ko
/lib/modules/5.10.83/kernel/net/netfilter/xt_dscp.ko

However, the mac described earlier does not distinguish between the two. The result of the mix firmware should be the following,

iex(19)> cmd "find / -iname xt_dscp.ko" # this firmware was made on ubuntu
/lib/modules/5.10.83/kernel/net/netfilter/xt_DSCP.ko
/lib/modules/5.10.83/kernel/net/netfilter/xt_dscp.ko

But on the mac described above, it will look like this

iex(1)> cmd "find / -iname xt_dscp.ko" # this firmware was made on mac
/lib/modules/5.10.83/kernel/net/netfilter/xt_DSCP.ko

Since these netfileter modules are not used, there is no effect on the operation. And if it is a module that is not used, we think it should not be included in this system in the first place (future work).

@takasehideki

I think v0.1.2 might resolve this issue, 'cause I removed configs which relates to xt_*.ko. Could you confirm it when you are free?

@pojiro Cc @kikuzo @kikuyuta Thanks so much! I've confirmed v0.1.2 could solve this issue in my environment. So I close this issue 🎉
