#1268303 — Bug#1119650: mdadm: "efivarfs: Unknown parameter 'relatime'" in initramfs

Package: mdadm
Version: 4.4-11
Severity: important
X-Debbugs-Cc: debbugs2025-10@wulf.eu.org

Dear maintainer,

my system boots from root-on-lvm-on-raid1-on-intelvroc.
The mdadm package installs two hooks into the initramfs to mount
/sys/firmware/efi/efivars and then scan for raid devices.

This mount command fails:

mount -t efivarfs -o rw,nosuid,nodev,noexec,relatime efivarfs /sys/firmware/efi/efivars

[     1.845553] efivarfs: Unknown parameter 'relatime'
mount: Invalid argument
mdadm: error opening /dev/md?*: No such file or directory

This leaves me in an (initramfs) shell, i.e. system won't boot.

I found two possible fixes:

* Remove the "relatime" parameter from the command and rebuild the
  initramfs. It appears like it's still mounted with "relatime" even
  without that parameter.

* Install busybox. It appears that its "mount" implementation does
  something different from the one provided by klibc-utils.

First aid if anyone is stuck in the initramfs:

(initramfs) mount -t efivarfs -o rw,nosuid,nodev,noexec efivarfs /sys/firmware/efi/efivars
(initramfs) mdadm --assemble --scan
(initramfs) exit

System should boot up.


If possible, could this bug be fixed in "stable" too, given that the fix
is probably small and isolated and it keeps systems from booting?


If this is actually a bug in klibc-utils, please forward my bug report.


Thanks
Jörn
