Attempting to merge sys-boot/grub-2.04-r1 with USE libzfs turned on results in multiple sandbox violations, all mkdir in /etc/exports.d but with a different grub-* command, like the following: F: mkdir S: deny P: /etc/exports.d A: /etc/exports.d R: /etc/exports.d C: grub-mkrelpath --help F: mkdir S: deny P: /etc/exports.d A: /etc/exports.d R: /etc/exports.d C: grub-mkrelpath --version Without this USE, GRUB merges fine.

Created attachment 660138 [details] tail-build.log.txt Here's the end of the build.log where the error happens.
Adding /etc/exports.d to the allowed sandbox list obviously allowed this to work, but I neither had a prior /etc/exports.d, nor did the merge create one. Very odd.
It's quite possible that ZFS itself is trying to do this: https://github.com/openzfs/zfs/issues/10785
Seems like an issue that should be addressed in libzfs.
I guess zfs version is 2.0.0-rc1? there's a PR fixing it https://github.com/openzfs/zfs/pull/10934 I can add it after it's reviewed/merged. workaround is simple enough, just creating /etc/exports.d we could add addpredict to grub, but it's not the correct solution.
