#### Modern file systems
I recommend using a modern file system like ZFS. It provides transparent block-level compression,
instant snapshots and full-disk encryption. Generally encrypting your root fs doesn't cost you

If you experience any issues after rebooting and need to fix something inside the chroot,
you can use the installer to chroot into an existing system. Run `./install --help` for more infos.
#### Q: ZFS cannot be installed in the chroot due to an unsupported kernel version
**A:** The newest stable ZFS module may requires a kernel version that is newer than what is provided on gentoo stable.
If you encounter this problem, you might be able to fix the problem by switching to testing by dropping to a shell temporarily:
```
# Press S<Enter> when ased about what to do next.
# This opens an emergency shell in the chroot.
echo 'ACCEPT_KEYWORDS="~amd64"' >> /etc/portage/make.conf # Enable testing for your architecture.
emerge -v gentoo-kernel-bin # Update kernel to newest version
exit # Ctrl-D
# Now select 'retry' when asked about what to do next.
```
#### Q: I get errors after partitioning about blkid not being able to find a UUID
