Merge 33319701ca into c946b13575 2024-11-22 11:05:58 -08:00
Christian Hesse c946b13575 link README.logs from tmpfiles.d/legacy.conf only if available
The file README.logs is installed only if SysVInit support is enabled.
Thus the link should depend on it as well.

man: split cryptenroll man page into sections (#35297) 2024-11-22 12:01:07 +00:00

Lennart Poettering e412fc5e04 userbdctl: show 'mapped' user range only inside of userns
Outside of userns the concept makes no sense, there cannot be users
mapped from further outside.
2024-11-22 11:28:17 +01:00
Lennart Poettering cc6baba720 cryptenroll: it's called PKCS#11, not PKCS11
In the --help text we really should use the official spelling, just like
in the man page.
2024-11-22 10:42:37 +01:00
Lennart Poettering 3ae48d071c man: add enrollment type sections to cryptenroll man page
We have the same sections in the --help text, hence we even more so
should have them in the man page.
2024-11-22 10:42:37 +01:00
Antonio Alvarez Feijoo 2ccacdd57c bash-completion: add --list-devices to systemd-cryptenroll
And also use it to list suitable block devices.

Luca Boccassi 33319701ca veritysetup: parse signature from DPS partition
If the signature is not specified manually, and sd-veritysetup is running
on a device, try to find the parent and if it's a DPS-compliant GPT
image with a signature partition, parse it and use it.
This allows automatically using the signature on boot, which allows
setting an IPE policy that enforces a validated signature on the
rootfs too.
