Garbled file names in the root filesystem

sez11a · May 27, 2025, 4:58pm

Hello,

Requirements:

I have Searched the forum for my issue and found nothing related or helpful
I have checked the Resources category (Resources Index)
I have reviewed the Wiki for relevant information
I have read the the Release Notes and Errata

OpenMandriva Lx version:

ROME

Desktop environment (KDE, LXQT…):

KDE

Description of the issue (screenshots if relevant):

Just noticed today (because I don’t cd to my root directory often) a whole bunch of garbled files in my root filesystem. I have no idea how they got there or what’s generating them:

Relevant informations (hardware involved, software version, logs or output…):

I installed ROME on this system about a month ago now. Encrypted system (required for work) with swap/hibernate and only efi, swap and / partitions:

Anybody know what’s going on here?

zeroability · May 27, 2025, 10:44pm

Can you walk us through the options you chose for encryption when you installed OMLx?

sez11a · May 28, 2025, 2:48pm

Certainly! I chose Erase Disk, Swap with Hibernate, and Encrypt System. I gave Calamares a password and that was it. Very easy.

I have noticed (in a VM) that after the 6.0 Rock release, the bug with having to enter the password twice (once pre-Grub, once post-Grub) is fixed. My system, however, still has that requirement. I have no idea if this is related, though. If there’s a way to fix it so I only have to enter the password post-Grub, that would be ideal, as this machine has a HIDPI screen, which makes it super-hard to see the prompt for the password.

You can try/verify the following fix:

LUKS password required twice on boot

enhancement [RFC] cooker upstream ROME/rolling devs

**OpenMandriva version**: OpenMandriva Lx 25.01 (ROME) Rolling **Describe the b…ug**: The password to unlock the LUKS volume is required twice on boot. **Steps to reproduce**: - Boot system - Enter password at GRUB bootloader prompt to unlock LUKS volume - Enter password to mount the root filesystem **Observed behavior**: LUKS password is required twice to boot the system. **Expected behavior**: LUKS password is required once to boot the system. **Additional comment**: Issue does not exist on Rock 5.0, on the same hardware.

I am not certain if the upstream with the fix was added or not. We are also discussing LUKS2. The last time it was enabled, it broke grub2 completely so we definitely need people willing to test that independently:

From the forum: https://forum.openmandriva.org/t/installing-openmandriva-on-luk…s2/6252/15 The following default configuration is provide for encrypted partitioning: https://github.com/calamares/calamares/blob/babaddffc39fa1a423c4f9714e8cf972f18d2af6/src/modules/partition/partition.conf#L90-L102 Investigate if this can be enabled without creating a breaking scenario with the bootloader (`grub2`).

But after doing some search sleuthing, it appears this may be intended behavior and you might have to manually decrypt:

https://linux.die.net/man/8/cryptsetup

I would suggest doing some more research to verify. The source of the information was this Stack post:

sez11a · May 30, 2025, 4:43pm

Thank you, @zeroability !

It took me a couple days to research some of this and do some experiments. In my scenario, I’m only doing disk encryption because my company makes me. They have a default Linux you can use based on Fedora, and when that’s installed, Grub just comes up, and you’re not asked for a password until after it attempts to boot the OS.

This tells me it must be acceptable to have an unencrypted /boot partition. I was able to verify this in a VM with the OM Calamares installer if I chose these options:

- 500MB /boot (no encryption) ext4
- 300MB /boot/efi (no encryption) fat32
- 8192MB linuxswap (no encryption) linuxswap
- / and /home (encryption) ext4

If I install with that partition scheme, I mimic the behavior I get on my company’s Fedora. I’m asked to decrypt AFTER Grub, in the graphical Plymouth screen. This is really what I want, because a) Grub decryption takes forever, and b) the machine they gave me has a HIDPI screen, and I can barely see the decryption request from Grub.

My next question is, can I convert my existing installation to this, or do I have to reinstall (which would likely solve the garbled file names problem I originally posted about)? My guess is no, because the automatic partitioning has an encrypted / and an unencrypted /boot/efi, so I’m guessing Grub needs to decrypt / before it can get to /boot/efi. But I’m not sure, and I’m not sure how to go about testing this.

This guidance may be helpful:

https://wiki.archlinux.org/title/Removing_system_encryption#Decrypting_LUKS1_devices_in-place

I would suggest reading the entire article as there may be other things you will have to do. This is new territory for me as I do not encrypt my PC’s.
