As seen on #perl6:
<audreyt> re MO hacking, will do that as soon as disk0s2: 0xe0030005 (UNDEFINED). goes away.
<audreyt> need to spend ~2hr running ddrescue
<putter> re disk, eep
<audreyt> since it's creeped into ~/.svk/ area and hence interfere with hacking
<putter> (image of audreyt watching disk progressively die, but thinking "no, it hasn't hit /svk yet, so it's not important", and goes back to hacking...;)
I would like to simply remark that putter++'s imagination was... entirely correct. ;-)
