- Hi,
+ [Impact]
+ The original report shows a scenario where clevis fails to bring up
networking in the initramfs, resulting in a failure to automatically unlock a
LUKS volume using a tang server. While it isn't clear how the problem manifests
(see Comment #2), it is clear from the user's description of a workaround that
the fix for bug 1896289. should also fix this issue as a side-effect. Without
truly understanding the root cause I'd normally not propose this for an SRU,
but here we're getting it "for free".

+ [Fix]
+ The issue is with how the function clevis_all_netbootable_devices() generates
a list of devices. It uses a `DEVICE="$DEVICE $device"` pattern, which causes
the first device to be prefixed with a space. The fix for bug 1896289 happened
to get rid of that space character in order to fix a cosmetic issue when
printing a warning:

- I have to fix eth_check()
- from
- ip link set dev "$device" up
- to
- ip link set dev $device up
+ [Test Case]
+ Confirm that automatic unlocking using a tang server works.
- to avoid error
- Error: argument " enp2s0" is wrong: "dev" not a valid ifname
