They are networked (I can reach them) and if really necessary I could get someone to power cycle them the next day, so not sure how far that counts as unattended. Remote hands so far have not been necessary though. Have seen uptimes over 3 months.
They do write logs (icinga/nagios, cacti, syslog for appliance) but don't get rebooted very often so not sure how much this says about the likelihood of eMMC corruption issues. I would expect ext4 to catch most of these though? The limited instability I have seen with BBBs is where wireless USB devices are used, but even one with two USB wifi adapters has seen uptimes over 50 days. I have yet to experience an eMMC or SD that becomes spontaneously unbootable.
