LUKS related directories in root of a Debian 11
Hi,
i am wondering what creates and touches on a Debian 11 system a lot of
empty directories in the /-Directory. The names indicate that they have
something to do with LUKS:
/1678114330.LUKS1_test_cryptsetup_defaults
/1678114331.LUKS1_test_with_twofish_cipher
...
/1678114341.LUKS2_test_cryptsetup_defaults
/1678114342.LUKS2_test_with_twofish_cipher
...
/1680340570.LUKS2_test_with_argon2_pbkdf
/1680340571.LUKS2_test_with_second_key_slot_and_first_slot_using_different_password
In total there are 115 of these directories. Currently all are empty.
One of them bears the timestamp of today's boot:
/1678114330.LUKS1_test_cryptsetup_defaults
(Its prefix number as timestamp says "Mon Mar 6 15:52:10 CET 2023")
A few bear the timestamp "Apr 1 2023" and most bear "Mar 6 2023".
One of the partitions on the system is indeed encrypted. But the
root filesystem is not. df says about both:
/dev/nvme0n1p2 479152840 92955444 361788004 21% /
...
/dev/mapper/daten 3778568692 1538634024 2047923672 43% /daten
So my questions are:
- Where can i learn about those directories ?
- Why are they located in / and not in some sub-directory ?
Have a nice day :)
Thomas
