Title:
  Kexec reboot doesn't work on 18.04 non-EFI system

Status in kexec-tools package in Ubuntu:
  Confirmed
Status in systemd package in Ubuntu:
  Invalid

Bug description:
  Unclear whether to report it against kexec-tools or systemd.

  After upgrading to Ubuntu 18.04, the „systemctl kexec” command gives the following error message:
  Cannot find the ESP partition mount point.

  What's interesting is that strace shows that systemctl tries to find
  the EFI partition before it emits the error message, like it was
  expecting an EFI system. My laptop is not capable of EFI, and it
  wasn't a problem for previous Ubuntu releases – the „systemctl kexec”
  command worked fine before.

  Here is my systemd version:

  root at thinkpad:~# systemd --version
  systemd 237
  +PAM +AUDIT +SELINUX +IMA +APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ +LZ4 +SECCOMP +BLKID +ELFUTILS +KMOD -IDN2 +IDN -PCRE2 default-hierarchy=hybrid

  And my kexec-tools version is 1:2.0.16-1ubuntu1.

  I attached an strace output.
