Minor problems

Talk status
This discussion is done as of 2021-10-27.
  1. I would replace "Now that the partitions are created" with "Now that the partitions have been created"
  2. I would add a comma to the following sentence (between "allocation" and "ext4"): "Instead of the classic ext2/3 bitmap block allocation ext4 uses extents, which improve large file performance and reduce fragmentation."
  3. I would replace "Apple's OSX" with "Apple's macOS" (see Wikipedia page)
  4. I would change "Similar to vfat above it does not store UNIX permission settings" to "Similarly to VFAT, it does not store UNIX permission settings"
  5. In the initial list of available filesystems, ext2, ext3, and JFS lack a link to their corresponding Gentoo wiki articles

-- Fturco (talk) 15:27, 3 June 2020 (UTC)

Suggested fixed applied except for the last one. ext2, ext3 have been removed from the handbook since they are antiquated at this point. See Special:Diff/1018938/1023993 for the fixes. --Maffblaster (talk) 16:54, 28 October 2021 (UTC)

Reiserfs is included in mainline Linux--Nikitastepanov (talk) 11:33, 30 August 2020 (UTC)

Updated --Grknight (talk) 13:41, 31 August 2020 (UTC)
Included in mainline Linux as of when? Does anyone have a link or official news item to support this? As far as I can see as of the most recent commit, reiserfs is not included in "mainline" Linux (nor has it ever been). The only way to have reiserfs version 4 it is to use the reiserfs patches on top of the mainline kernel. I'll backpedal any changes to the contrary for now, Brian Evans (Grknight) can revert my backpedaling if I'm mistaken. Thank you! --Maffblaster (talk) 18:25, 31 August 2020 (UTC)
Upon further review, I was mistaken. reiserfs version 3 was and has been included with the mainstream Linux and appears to be somewhat maintained. Version 4 (the latest version) was the object of my thoughts when I was saying it has never been included in mainsteam (above). reiserfs v5 was announced late (Dec) 2019, which is not included (yet) in mainline either. The ebuilds for userspace utilities do not note they utilities for reiser v3. I could see users getting confused during the installation process for if they choose reiserfs. Still wouldn't recommend as a handbook suggested path, but I think we can remove the warning if we note this is reiserfs v3 specific. --Maffblaster (talk) 20:44, 31 August 2020 (UTC)

GPT: Note about Windows needs to be corrected...

Talk status
This discussion is done as of 2024-05-11.

Under GUID Partition Table (GPT), the note says:

Using GPT on a BIOS-based computer works, but then one cannot dual-boot with a Microsoft Windows operating system. The reason is that Microsoft Windows will boot in UEFI mode if it detects a GPT partition label.

This is wrong, because the logic is reversed. The boot mode is not determined by the partition table. At the stage where Windows (or its boot loader) takes over, the boot mode is a given. (And "Windows will not boot in UEFI mode if it detects a GPT partition label"... It simply cannot change the boot mode that easily...)

The opposite is true: When Windows is booted in BIOS mode (UEFI CSM), it will refuse to boot unless the system partition is a legacy MBR partition. Likewise Windows will refuse to boot in (U)EFI mode when the partition is not a GPT partition. This is even then the case when the partition used for \WINDOWS is absolutely accessible during the boot process (in which case the refusal to continue is simply a design decision)...

Correct is:

  • BIOS → MBR
  • (U)EFI → GPT

Wrong is:

  • MBR → BIOS
  • GPT → UEFI

However, it is also true that certain UEFI implementations will start the CSM if a (hybrid) MBR (or at least more than just a protective MBR) is detected. Notably certain Macs use this method, most likely for Boot Camp to function correctly. Most PCs use a manual method: if a CSM is loaded or not has to be enabled or disabled in the firmware setup. Thus UEFI on a PC will always be in (U)EFI mode, even with an MBR, when the CSM is disabled in the firmware setup. And the boot option for a legacy MBR, with CSM enabled, will always end up in BIOS mode, which will only load the boot block, block 0, which is the (protective) MBR, even when using a GPT (like with GRUB and a "BIOS boot partition", or to e.g. boot Windows in legacy/BIOS mode using hybrid partitioning on a Mac).

See also: GRUB#Dual-boot with Windows

Suggestion for correcting the note:

Using GPT on a BIOS-based computer works, but then one cannot easily dual-boot with a Microsoft Windows operating system. The reason is that Microsoft Windows has to be booted in UEFI mode to use a GPT partition as its system partition.

Luttztfz (talk) 10:46, 10 October 2021 (UTC)

TL;DR:
Under GUID Partition Table (GPT), the note says:

Using GPT on a BIOS-based computer works, but then one cannot dual-boot with a Microsoft Windows operating system. The reason is that Microsoft Windows will boot in UEFI mode if it detects a GPT partition label.

This is false — the firmware determines whether the OS boots in UEFI or BIOS mode, usually based on whether CSM/legacy boot is enabled. What Windows actually does is refuse to boot if it's not on a BIOS+MBR or UEFI+GPT setup.
Proposed changes - Please make edits here until a final revision is agreed upon.

Using GPT on a BIOS-based computer works, but the user won't be able to dual-boot with a Microsoft Windows operating system, since Microsoft Windows refuses to boot from a GPT partition when in BIOS mode.

Dropping ReiserFS

Talk status
This discussion is done as of 2022-07-14.

With the recent Phoronix news, I would suggest dropping ReiserFS from the handbook. I made a temporary entry here but ultimately feel it should just be removed. Please provide input. --Grknight (talk) 14:11, 4 April 2022 (UTC)

Good suggestion. No one else commented; it's just me and you! Mention of ReiserFS has been removed in this change Special:Diff/1057545/1077314. Thanks, Brian Evans (Grknight) . --Maffblaster (talk) 01:13, 15 July 2022 (UTC)
