 |
|
It's been a while installing Gentoo, but tried yesterday, and restarted today.
Following the Handbook for a EFI/GPT system and everything works great until installing GRUB2
| Code: | (chroot) sysresccd ~ # grub-install --target=x86_64-efi --efi-directory=/boot
Installing for x86_64-efi platform.
Could not delete variable: Read-only file system
efibootmgr: ** Warning ** : Boot0003 has same label gentoo
Could not prepare Boot variable: Read-only file system
Installation finished. No error reported.

Boot is mounted, my fstab
| Code: | /dev/nvme0n1p1 /boot vfat rw,defaults,noatime 1 2
/dev/nvme0n1p2 none swap sw 0 0
/dev/nvme0n1p3 / ext4 rw,noatime 0 1
/dev/nvme0n1p4 /home ext4 rw,defaults,noatime 0 2
|
and mount
| Code: | (chroot) sysresccd /boot # mount
/dev/nvme0n1p3 on / type ext4 (rw,relatime,data=ordered)
/dev/nvme0n1p1 on /boot type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,errors=remount-ro)
/dev/nvme0n1p4 on /home type ext4 (rw,relatime,data=ordered)
/proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime)
securityfs on /sys/kernel/security type securityfs (rw,nosuid,nodev,noexec,relatime)
debugfs on /sys/kernel/debug type debugfs (rw,nosuid,nodev,noexec,relatime)
configfs on /sys/kernel/config type configfs (rw,nosuid,nodev,noexec,relatime)
fusectl on /sys/fs/fuse/connections type fusectl (rw,nosuid,nodev,noexec,relatime)
pstore on /sys/fs/pstore type pstore (rw,nosuid,nodev,noexec,relatime)
efivarfs on /sys/firmware/efi/efivars type efivarfs (ro,relatime)
udev on /dev type devtmpfs (rw,nosuid,relatime,size=10240k,nr_inodes=8231582,mode=755)
mqueue on /dev/mqueue type mqueue (rw,nosuid,nodev,noexec,relatime)
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000)
shm on /dev/shm type tmpfs (rw,nosuid,nodev,noexec,relatime) |
I have disabled secure boot in UEFI on my Motherboard.
Have i missed something fundamental?
E:
As a sanity check i checked my /boot with tree
| Code: | (chroot) sysresccd ~ # tree -L 2 /boot
/boot
├── EFI
│ └── gentoo
├── System.map-4.12.12-gentoo
├── config-4.12.12-gentoo
├── grub
│ ├── fonts
│ ├── grubenv
│ ├── locale
│ ├── themes
│ └── x86_64-efi
└── vmlinuz-4.12.12-gentoo
|
It seems pretty messy?
Well, sometimes the easiest solution is applicable. I remounted efivars with
| Code: | | mount -o remount,rw /sys/firmware/efi/efivars |
and the same with /boot and tadaa.
Sorry for the buzz.
See you soon again. |
