initramfs move

the initramfs move (rename) does not seem a necessary step? to update the grub.cfg, so that is GRUB will see newly named initramfs, running grub-mkconfig would be better. And name should not be relevant, then. Oleg.

Comments on the Installation Guide

A few points regarding the new instructions of the "ZFS Install Guide" (by Nikos Alexandris):

- using the suggested ubuntu version, and after adding enabling the universe repository sources, poses a (minor) problem when trying to update. The proble and the solution described at http://askubuntu.com/q/761592/48282.

- `grub-install /dev/disk/by-id/ata-...` failed for me initially. The newly created partition, after `sgdisk -a1 -n2:48:2047 -t2:EF02 -c2:"BIOS boot partition" /dev/disk/by-id/ata-...`, was not present under `/dev/` as `sda2`. The "fix" was 1. re-read the partition table without rebooting, i.e. `partx -u /dev/sda`. 2. re-emerge grub to support for i386_pc -- if I remember well... `USE="i386_pc" emerge -av grub`.

• partx -u /dev/sda added to guide. Tassietux (talk) 11:23, November 2, 2016 (UTC)

- Although all of the rest seem(ed) to be ok (ie GRUB 2 support for ZFS, verification of existence of `/boot/grub/i386-pc/zfs.mod`), trying to (re-)boot, fails at the step of importing the zpool. The zpool failed, initially to be exported. I re-booted the live USB stick, chrooted all the way from the scratch, exited, exported the zpool successfully. Still no success to boot.

• Have you seen http://www.funtoo.org/index.php?title=ZFS_Install_Guide#Will_not_mount_on_first_reboot.3F ? This may help you find what went wrong. Tassietux (talk) 11:23, November 2, 2016 (UTC)

• Problem resolved, I guess something to do with re-compiling the ZFS modules. --Nikosalexandris (talk) 15:07, November 26, 2016 (UTC)
