[systemd-bugs] boot hangs: systemd[1] - nfs branch is not exportable

[Vladimir Elisseev]

Hello,

Updating systemd-188 to >=193 leads to boot error: immediately after
issuing switch_root systemd hangs with the message "systemd[1] - nfs
branch is not exportable", though system can be booted properly if using
the SysV init. I've been using AUFS with NFS root (NFS ro with NFS rw
branches) for a long while and lately successfully with systemd until
got this error. I'd appreciate if somebody can provide an explanation of
the reason why this happens.

Regards,
Vlad.
