zpool: add optionsAfterCreate...
Not sure about the best implementation here yet. I'd like to use disk encryption with ZFS and existing disko facilities work fine to set it up, but we obviously can't use keylocation=prompt during disko formatting. So unlocking fails on boot if the file referred to by keylocation isn't included in the initrd. Ideally I could use keylocation=file://tmp/disk.key during partitioning, but set keylocation=prompt right after that. example usage: ``` rpool = { type = "zpool"; mode = ""; options = { ashift = "12"; autotrim = "on"; }; optionsAfterCreate = { keylocation = "prompt"; }; rootFsOptions = { encryption = "on"; keylocation = "file:///tmp/disk.key"; keyformat = "passphrase"; compression = "zstd"; acltype = "posixacl"; mountpoint = "none"; canmount = "off"; xattr = "sa"; dnodesize = "auto"; normalization = "formD"; relatime = "on"; }; ```
