Updated Cygwin on my XP box. Thought because it stopped several
times before finishing and having to choose a different server, that it
had something to do with it. Apparently not. Searched the Cygwin
mailing list archives and found the following:

Fixing /etc/profile

You just copy C:\cygwin\etc\defaults\etc\profile over C:\cygwin\etc\profile
and restart cygwin. After that, everything goes back to normal. Just another
day in puter paradise. Speaking of which, I’m always bragging about how I
never have to reboot OpenBSD all the time like I do “Windoze”. Sitting here
this morning, reading the news in Firefox on the OpenBSD box, and BOOM,
down she went! I’ve read all sorts of problems and responses in the OpenBSD
mailing lists with spontaneous reboots, and nobody wants to think their hardware’s
crapping out, but in my experience, that’s almost always what’s caused it on any
of my boxes. Case in point: Same box, last year maybe, or earlier this year, everytime
I’d drag a large file across from XP to some dir on the OpenBSD box, it’d reboot.
Upon careful examination of the mobo, turned out to be some leaking capacitors.
Changed out the mobo and, while I was at it, put in a new power supply too. It sure
didn’t last very long. All boxes here are hooked into UPS’s, which is a prerequisite
around this area. The power company is always dropping power off, especially since
Katrina came to see us in 2005. I guess it’s a moot point, though. I’ve always had
good luck with power supplies, but I guess I just got a bad apple out of the barrel
last time.
