Hello,

kmod version 28 adds support for zstd. The support is optional but when
not enabled the depmod test which unconditionally tests zstd fails.

As kmod supports more and more compression methods I think it is not
reasonable to expect everyone has all copression libraries available.

Do you think it is reasonable to fix the tests to only use teh
compresion methods enabled by configure?

We specifically added support for skipping tests when the build
options would imply that the test
would fail. It should not be failing, we probably screwed something up.

I noticed that and backported both related patches during backport:
847247a testsuite: Automatically skip tests that fail when sysconfdir != /etc.
b5683f4 testsuite: Add facility to skip tests.

but it failed.

Also running master with:
./autogen.sh && ./configure CFLAGS='-g -O2' --enable-debug  --with-zstd --with-xz --with-zlib --with-openssl && ma && ma check
fails on testsuite/test-depmod:
