What might be the recommendation file system for a grub partition, so that it will be accessed from most of linux or windows or osx systems.
1 Answer
I'd stick to the defaults, an ext* filesystem. Personally I use ext2 because the journaling function of ext3/ext4 can make mounting the filesystem slower (observed on a flash memory stick). AFAIK journaling can be disabled for ext4, but since I was happy with ext2 I did not consider ext4 for read-only partitions like /boot
.
- MacFUSE seems to work for accessing ext2/3 partitions (read+write)
- Windows supports ext2 (and ext3 without journal) with the driver from http://www.fs-driver.org/ (see also The best choice of linux file system and software that can be accesed from Windows)
Avoid filesystems that do not support Linux file permissions like NTFS and FAT*. Although all files are owned by root and most of them have permissions 644, lack of proper permissions support could set inappropriate default permissions for the files.

@Starx: that's true, but FAT does not support Linux file permissions. All files on the filesystem will have the same owner and permissions. For new installations, I'd use ext*. If properly configured (mounted with
dmask=022,fmask=133,uid=0,gid=0
), filesystems like FAT are fine in the sense that it can be booted from. On my installation,vmlinuz
cannot be read by regular users. If you're using FAT, this restriction is gone. Jul 26, 2011 at 12:08
