Hello all, I've just finished up a UEFI install of funtoo, but when I rebooted the boot partition wouldn't mount, giving me the following error:
Code:
mount: unknown filesystem type 'vfat'

I've made sure my fstab file was correct, as well as the kernel configuration - I just can't think what the problem is.
Does anyone have any idea what could be wrong?

Bladesy ... yes, you're asking in the wrong forum, you should be asking at funtoo forums. Requesting mods move this to "Unsupported Software".

Moved from Installing Gentoo to Unsupported Software. Not about Gentoo so it fits better here.

Oh, I see - sorry about that, I just thought that gentoo and funtoo were very similar, and that it would likely be the same solution if it occurred on a gentoo system.

Bladesy ... that's true, it may be similar, but none of us gentoo users would know if this is the case or not ... and that's the problem really (besides the fact that when you get the code, you don't also get the community that supports that code).

Anyhow, I don't see why you're mounting the ESP at boot ... there is no need to ...

Code:
# awk '/vfat/{print $4}' /etc/fstab
noauto,defaults

As for the filesystem itself, you should check its enabled in the currently booted kernel:

Code:
# zgrep VFAT /proc/config.gz
CONFIG_VFAT_FS=m

You should also check that it is infact FAT32 (the specified filesystem for the ESP)

Code:
# file -sL /dev/sda1
/dev/sda1: DOS/MBR boot sector, code offset 0x58+2, OEM-ID "BSD  4.4", sectors/track 32, heads 16, sectors 409600 (volumes > 32 MB) , FAT (32 bit), sectors/FAT 3151, reserved 0x1, serial number 0x70d61701, label: "EFI        "

I understand what you mean about the differences between the gentoo and funtoo - it turns out funtoo's boot-update program wasn't properly set up. But not I believe I have a more general problem of a kernel panic - the system does start anymore because of this. I get the following error:
Code:
VFS: cannot open root device "sda3" or unknown-block (0,0)
please append a correct "root=" boot option
kernel panic- not syncing: VFS: unable to mount root fs on unknown-block(0,0)

My understanding of this is that the kernel can't see the disk, is this right?
