comment forward vs. backward symlinks: administrative practice?
@Astara, udev has been used on all distros in the last 5+ years or so.. anything debian or redhat derived for years has not booted without /usr. Scripts have always had to specify the absolute path to their interpreter on the shbang line, no path is searched. Redhat seems to think that going with /usr instead of / is good for being able to mount /usr as a shared read only fs, but I don't quite buy that argument since you could have a shared read only / instead.

comment How to determine whether a linux filesystem belongs to a running system or not
The question was whether the filesystem is mounted, not whether it is mounted as the root directory.

comment forward vs. backward symlinks: administrative practice?
@Astara, udev has relied on numerous components in /usr for some time, so even single user mode can not function without it. systemd requires /usr as well.

comment Can I put 2 disks into a raid-0 array without reformating the FS?
Note that you don't format sda, you just add it to the array.

comment lost superblock in md raid
Using metadata format 0.9? Last time I tried it wouldn't work; I had to rebuild the array using 1.2. Discussion on the linux-raid mailing list seemed to indicate this was to be expected.

You actually can't grow arrays that store the metadata at the end; the kernel won't move the superblock.

comment Why does this work: “cp image.bin /dev/mapper/loop0p1”?
@frostschutz, they are if you boot with the loop.max_parts argument, or you can use partprobe or partx to activate them otherwise. There's no need to involve the device-mapper.

Are you sure you don't mean /dev/loop0p1? There won't be a loop in /dev/mapper unless you have done some hacking around with dmsetup.

That does sound like a bug in busybox...

comment Is there a good drive torture test tool?
the problem is proving that it is a bad drive ( or really, a bug in the firmware ) and not say, a bug in the kernel. If it were a bad cable, it would manifest as sata ecc errors rather than random silent corruption.

comment Is there a good drive torture test tool?
the errors aren't detected by the drive, hence the need for a test tool. It manifests itself by the filesystem being remounted ro, and e2fsck finding and fixing lots of errors in the metadata. Also I've had some of my git repository pack files corrupted. It's a silent corruption that happens maybe once every month or two. At first I thought it may be a bug involving TRIM since I don't recall this happening before I enabled it, so I turned it back off and it's still happening.

@WingTangWong, wow. I've ready that many SSDs screw up when they lose power, but when asked to go to sleep? That's one buggy drive. I'll keep an eye out for this. I'm using Linux and don't have it sleeping except maybe when I suspend the system...

@dustin, so replace the existing alias? Also if you add "--alternate-editor=" to the emacsclient alias, if there isn't already a running emacs server, it will start an emacs daemon and connect to it. Then you don't need to bother with server-start.
