[systemd-devel] systemctl kexec failed with error if /boot/efi on the mdraid

[Adrian Vovk]

Hello,

UEFI doesn't support RAID for the ESP, and neither does systemd. So it's
not unexpected that systemd is unable to find your ESP: your ESP isn't a
valid ESP.

You may be able to work around your issue by setting an env var:
SYSTEMD_RELAX_ESP_CHECKS=1

Best,
Adrian
