> I have had so many random and weird failures with systemd
A favourite at the moment is one of four apparently identical desktops machines, one of which is stuck in the boot process allegedly trying to make a network connection, either before or after connecting to an NFS server. All is fine in recovery mode and it works as expected, but when systemd has full rein, it spits a dummy and won't tell me why. It may be logging loads in its binary database, but if it won't condescend to letting you log in to look, it's no use. This is not progress.
