"webkit-gtk" was one that took me a few tries to get to compile completely. ymmv. Obviously many things have been resolved that are listed in the thread. " have you considered to stabilize gcc:4.9 instead possibly 4.9.2 ? I'm not really suggesting to do so, but seem that most of the problems of 4.9.1 are the same of 4.8.3 so maybe it's worth considering. " that said 4.8.3 is marked stable by the devs, but a large part of that is 4.9.x is needed by some "key" codes coming down the pipe. No, I did not write thus down, just made myself a mental note up upgrade everything to 4.8.3 in preparation for 4.9.x.

Um, Tomas's little one-liner: lsof -n | grep 'DEL.*lib' revealed far to much to deal with. I got lib issues coming out of my arse (I've been hacking at a few things I do not fully understand (wink wink :: nudge nudge) ? > Bear in mind that some of what checkrestart reports is unimportant > anyway.

My need to reboot is because I've been noodling around with many many things. My current desktop: lxde is crippled and deprecated. Lx1t-0.8.0 is in the tree now, but masked waiting on another package or 2 to be tweaked. > Yes, things may be a little different with 4.9, but the last time a > rebuild was really required was,AFAIR, somewhere around 3.3. OK, so I reboot workstations more often than you. I hope that does not upset you? Yes, I've kept workstations online for over a year more times that I can count (fingers and toes). And when the reboot comes, It's a day or 2 fixing things, imho. YMMV. A judicious reboot now and again, timed well, is keenly a good idea, imho. ymmv. Besides I'm an old FT via redundancy, kind of guy; aka I *always* have spare systems, ready to go. On the server side. When I have to be "responsible" for servers others use, I *always* have duplicated hot spares, or I don't do it. I'm not saying that other should/have to do what I do. I'm very lazy and only get lucky when it counts. No I'm too forgetful to be considered smart anymore. So, I use spare hardwares, boot them up and away I go! I live in Florida; so the power failures can "jump" UPS's, ethernet cables and all sorts of strange issues, not just admin issues dictace FT via redundancy for me. I may just move my shop onto a sail boat, so then I'd have metal_chloride issuse to deal with...... So, via hardware redudancy, as thecomplete system level, I can diagnose failures at my liesure, sipping coffee, wine or a beverage that would make Alan crazy (quite a few of these....). I deeply appreciate your concerns over the admin skills of an old_fart.... RFC 5798. cheers? James
