> People are unreasonably tribal about file systems. I think it's probably worse than usual with ZFS, mostly for two reasons: a lot of hype (justified or not) early on its life, leading to hype aversion and/or backlash, and a "sour grapes" effect because its license ensures it will never (or at least until its copyright expires) be merged into mainline Linux, so those who can't or won't use it (due to a need or desire to run only mainline Linux kernel code) feel left out and/or get annoyed at seeing it pushed as the best thing since sliced bread all the time. Adding to that, its main competitor (btrfs) is known for having had (real or perceived) reliability issues early on its life, making its use more controversial (and its proponents more defensive at seeing the same reliability issues being raised all the time). And file systems are important, since people are reasonably concerned about the integrity of their data. They are also not easy to migrate (other than a rarely used tool to migrate in place from the ext2/3/4 family to btrfs, migrating filesystems usually requires dumping and reloading the whole data), making the choice of filesystems an important decision.
