I followed the steps in the FAQ for setting up full disk encryption.
Everything goes according to plan until I attempt to write zeros to the
first megabyte of the new pseudo-device; as you can see below, dd informs
me that the file system is full, that there is no space left on the device.
Interestingly, the last line of dmesg is also "uid 0 on /: file system
full". I've retried this with 5.9 and -current, but the outcome is the
same. I've also tried rebooting after disklabel and bioctl. I have pasted
below the relevant sequence, followed by the full dmesg.
