comment Can't start Ubuntu VM on VirtualBox 5.0.14
@neuron Yeah, laptop's (host machine's) BIOS. You probably want to mention that the VirtualBox 5 upgrade broke it in your Super User post...

comment Debian: Order of DNS servers when using VPN
Are all of the internal names under one or a few domains? I.e., could you say "use the external servers for everything, except *.internal.foo.com and *.secret.bar.com"? (This is easy to configure with dnsmasq).

Also plopping virtualbox ubuntu tried to kill init into Google gives some things to try... Sounds like accidentally having a BIOS option set wrong can cause this.

@neuron that sounds distinctly like your VirtualBox host system (Windows, or VirtualBox itself) is broken somehow, and it's not really a Linux problem. You might want to try asking Super User.

BTW: Where did this Ubuntu VM come from? Did you download a pre-installed VM image, or are you using e.g., the DVD image to attempt an install?

comment Can't start Ubuntu VM on VirtualBox 5.0.14
I'm looking at it frame-by-frame, can't go any slower. One frame has 13.806869 at the bottom, the next frame as 13.841325 at the top. Probably some messages should have been between those. This video manages to give a kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004 So at least that's something...

comment Can't start Ubuntu VM on VirtualBox 5.0.14
Unfortunately the video didn't capture it—it scrolled by more than one screenfull between the two frames. I'm not sure, is it possible to use a serial console in VirtualBox? Or just configure it to have a bigger "monitor" attached to it (thus giving more lines on screen at once)?

comment Can't start Ubuntu VM on VirtualBox 5.0.14
The kernel crashed for some reason (kernel panic)... unfortunately part of the message has scrolled off the top of the screen. Any way to capture the earlier messages? Hard to figure out what's going on without them.

comment Cannot remove file: Read-only file system
Check lvdisplay CRST-Web-vg/root to see if the logical volume is set read-only. Actually check lvs as well, to see if (for example) you have a snapshot that filled up. I wouldn't recommend a reboot before figuring out why the roootfs has gone read-only—high risk of the machine not coming back from the reboot (hope this warning isn't too late.)

comment Why does the cd command handle STDIN different than other commands?
echo 'hi' | cd / produces no errors here with Bash on Linux (though nor does it change the current working directory, as I'm sure is explained somewhere else on the site). Which shell are you using that's giving an error? Or is this a question about what's allowed per POSIX standards?

Is that < at the end of the line a typo in your question?

@Cestarian if that winds up working, please post it as an answer.

@RinaldiSegecin It sounds like you should try ffmpeg w/o the -rtsp_flags listen part.

comment Mount a large squashfs in a way that allows random writes (to a separate filesystem)?
Yeah, though that's tiny so you could just let overlay etc. take care of that. I'm not sure if pg can actually run w/o writing to the data files.. Also, any reason for it to be a squashfs? Could it be something typically writable like ext4 instead?

Odd that it needs to write. Have you tried default_transaction_read_only = on; in your PostgreSQL config? Also, move the WAL logs—they may need to be writable.

comment Run at command when computer is sleeping
I've seen it in desktop BIOSes as well, and Intel has something called Intel Smart Connect which does this in a lot of their current chipsets, unfortunately no Linux driver for it.

comment Run at command when computer is sleeping
The BIOS ought to be able to schedule a time to wake at, that's easier than an external WOL packet. But I'm pretty sure at doesn't do so.

comment Major and minor numbers of a partition
@Tim we probably should head over to chat with any further followups. (2) /proc/partitions only lists major numbers. The statically-assigned ones are assigned for both major and minor. 8,0 is always the first HDD using the sd subsystem, 8,1 is always the first partition on it, 8,2 always the second partition. That's how he new what 804 was. When needed, both major and minor numbers are dynamically assigned.

comment Major and minor numbers of a partition
@Tim (3) sda, sdb, sdc were basically assigned in order. It's the lowest-numbered sd, that's why it's sda. [Though I guess if somehow they managed to assign <8 to another sd block, they'd not change the names.] That's what I meant by first in the file. The lines are in order (at least on my machine), sorted by the major number.
