Default Bug#552810: initramfs-tools: Localtime not set during initramfs boot leading to wrong fsck.ext4 errors

Package: initramfs-tools
Version: 0.93.4
Severity: important

*** Please type your report below this line ***

After a power grid problem in my neighborhood, my workstation
rebooted and detected problems in the ext4 LVM volumes.

It appears that after a manual fsck.ext4, these problems were
trigerred because of a mismatch between the localtime and the time
set during initramfs boot sequence (probably the bios time).

The journal entries timestaps were simply offseted by one hour. This
matches exactly the difference between the my bios time (set to UTC)
and the Europe/Paris locatime my box uses.

I think it would be good to set to the correct locatime before running
disk checks that depend on the machine time. Otherwise it triggers
errors that cannot be skipped automatically when they could be.

initramfs does not do *any* fsck.

also please just use UTC everywhere, this looks more like a
user support question those are to be asked in a debian user
mailinglist. thanks

reassign 552810 util-linux
stop

please also keep bug report on Cc, this was not a personal
discussion, thanks.

you might want to report which version of util-linux you used
if you want to start a conversation with them. not sure i'd
see any bug right now, but i'm not util-linux maintainer
