comment forward vs. backward symlinks: administrative practice?
@MartinSchröder, yes, this conversation is about Linux.

comment Enforce strict outbound ports (or ranges) for protocol
The answer is no because the kernel has no idea what protocol is going to be used when you open/connect the socket.

comment what's the best way to chainload this
@RoelofWobben, you boot linux directly, skipping extlinux.

comment What are /dev, /run and /run/shm and can I resize them?
@h7u9i, it is your root filesystem that is full; ignore the others.

comment How to use DD to clone a partition off a disk image?
kpartx is for LVM. partprobe will also do the job, from the parted package.

comment Grub2 failing to update
What does pvdisplay show? My guess is that you were using LVM on the old drive and yanked it out without telling LVM to remove it, so now it's still looking for that disk.

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.

comment lost superblock in md raid
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.
