Earlier today, I ran sysupdate on a Thinkpad T23 running 9front-3196.bf2df3ad17fa and rebuilt from source, as shown in the 9front wiki.
Later, I edited /lib/ndb/local with sam to specify a different ntp server. After writing the change, closing the file, and quitting sam, I restarted with fshalt -r. After the restart, the machine's name had defaulted to cirno, and all dns lookups seemed to be failing. I checked /lib/ndb/local to see if I'd accidentally changed more than I thought, and the whole thing had been replaced with what looked like C source I'd been looking at, earlier. (Not the whole file, just the last ~20 lines.) I copied another machine's /lib/ndb/local onto a flash drive, copied it to /lib/ndb, modified it to suit the Thinkpad with sam, again, and restarted with fshalt -r. /lib/ndb/local got clobbered again, except this time, it was overwritten with something having the general appearance of line noise, heavy on unprintable characters. I repeated the process of reconstructing /lib/ndb/local from another box, only this time, I used ed instead of sam, and all appeared to be well, after restarting. Any ideas what went wrong? Trying to figure-out whether this is a DDTT situation, or if I should worry that something got corrupted in the update process, or that my recently installed SSD might have issues.
