 |
|
| This is my sixth installation of Gentoo. However, I forgot to format the partition as ext4 (or I don't remember) and now I have Gentoo installed on a FAT16 partition. What problems am I going to experience if I keep using the FAT16 partition? Or is it basically the same as ext4? |

| On a FAT partition you have not the read/write/execute permissions of an ext4 parition. |

When I wiped off the entire partition table with my windows 7 installation disk, I created 3 partitions. 2 of them are in use by windows. I forgot to run mkfs.ext4 before installing gentoo on it. Now, fdisk -l shows the partition on which gentoo is installed as "Fat16". However, in my fstab I have this:
| Code: | | UUID=682ed4c7-dc15-4c61-8a89-11aa7c87f86e / ext4 noatime 0 1 |
Am In trouble?
Edit : blkid shows the "TYPE" as ext4.
| Code: | | /dev/sda3: UUID="682ed4c7-dc15-4c61-8a89-11aa7c87f86e" TYPE="ext4" PARTUUID="0c1654bb-03" |

NaniBot,
Almost nobody cares about the filesystem type is the partition table.
There are a few exceptions that need not concern us here.
You can change the partition table to show Linux if you like but it will work as is.
FAT filesystems do not support symbolic links, so it would be a real challenge to actually install Gentoo on FAT.

So, the partition's type is FAT16 but the filesystem on it is not FAT16. Thanks for the explanation.  |

| Furthering the furthermore, FAT type filesystems can be coerced into supported UNIX style permissions; though, unless there is some need to use them that way, it is generally best to not do so. |

Not to be pedantic (because I can't) but there was something. I remember something like "slackware on dos". and it was a loadlin thingie that made linux slackare work on windows (fat). Nope I googled that. such fun times. forget I said anything.
EDIT: I'm sorry. But it's the only time I seen linux and windows mixed on the same fs. and it was so many years ago  |
