Read-only mount attribute not remembered across reboot

[thebuck]

R1beta4tc0, automount settings:

• automatic mount: (1st) do not auto-mount
• mount at boot: (2nd) mount previously mounted disks

But my previously read-only mounted EXT filesystem is mounted read-write on next boot.

At the same time another previously not-mounted EXT is correctly not mounted.

Haiku booted from a MBR partitioned thumbdrive (with handcrafted MBR, BeFS partition extracted from iso, dd'ed to partition, makebootabletiny).
Set failsafe video in bootmenu.
x86_64.
MBR partition table where the EXTs reside.
Traditional BIOS.

I do not know of any working hrev.

Increases chance of data loss, so setting to high priority. Guessed component.

Does it work on beta3? Or is there the same behavior?

[thebuck]

Same behavior on beta3.

[Back on B4TC0] Same also with:

GPT partition table
+ NTFS (Windows (C:), but not the Recovery which can only mount ro)
+ FAT32 (the EFI system partition)
+ EXT4

On this machine, R1beta3 cannot get to a working desktop (I believe it worked in the past, however...)

[thebuck]

NO DIFFERENCE in /Haiku/home/config/settings/mount_server (view BeFS using Linux) after having mounted ro versus rw.

Please attach the output of message ~/config/setting/mount_server.

Mounting did not update the file, so this is from after a reboot

[Jim906]

The mount server's MountArchivedVisitor looks for a mountFlags member of this settings message before mounting a partition, but ArchiveVisitor::Visit isn't adding this member to the settings.

I uploaded a possible fix: ​https://review.haiku-os.org/c/haiku/+/6080.
