Hi Max !
What the Hell are you doing ?

NEVER CHANGE A RUNNING SYSTEM .

So.... your Problems arose since a Kernel Update .....before this... everything went fine???

No Backups of your former Configuration/ Operating System? (menu.lst------changes FOLDER/FILE?---01-filesystem.squashfs ) ???

I dont have absolutely no clue how to handle Kernel Updates ......(did it once out of curiosity .......but can`t remember ).
But i backed-up the whole old OS in Case something went wrong .

Maybe it would help if you show us the actual Content of your casper Folder and your actual menu.lst.
Is your changes FOLDER/FILE on the same Device/Partition as your casper .Which type of Partition ext2/3/4 or fat or NTFS ?

Respectfully Guys, I know wot I know, which is enough 2 be Dangerous Wink

& I Certainly Wish I knew as much as you Guys about Linux, Ooh the Pain of the Learning Curve! Please eXcuse my Frustration, But Really this isn't as Tragic as 50 Deaths from Terrorist Attack Down South on the Mainland 2 Days ago

There is something "bloody" satanic wrong with your Politicians ......like her in Europe too......maybe i am paranoid ....but looks like a planned Genocide to "white" Europeans .Looks like a "Global" Plan.

Don't know how you did the kernel upgrade, anyway, the option from Menu > Upgrade Kernel used to work fine but now doesn't work anymore, so sorry if that's the reason for your trouble.

Yes, entirely out of place and off topic, and being a thread about Xenial Dog couldn't/shouldn't be answered here, and whilst I don't understand your ramblings, they look very wrong to me - but please take such comments (if you feel the need to make them) to Off Topic Area since don't want to read them when browsing about Xenial Dog, backi.

Hi Fred,

I'm playing/experimenting with overlayfs in Void Linux. Wondered if it is enabled in XenialDog64? When I tried simple overlay with xenialdog64, per the stuff I'm doing in void, it didn't work. However, it may be that I was trying to use it on a filesystem that was already an aufs layer (I'm not planning to use aufs with void).

So for now, just wanting to know if overlayfs enabled in XenialDog64 kernel.

wiak

EDIT: Sorry, meant to post this in XenialDog64 thread (using wrong thread) but sure you'll see it anyway. I'm aware, by the way, of the disadvantages/advantages of overlayfs compared to aufs support of layering, but I'm only interested in overlayfs for future work of my own since not enough time in the day to keep track of alternatives that weren't adopted for inclusion in kernel.

It's included in the kernel but not activated when using porteus-boot.
Btw, I expected that Xenialdog would boot with overlayfs when using "casper-boot", but just tested and it's not working, only aufs works (must add union=aufs to the kernel command line)
Don't know what you're trying to do, but it may work if you do a modprobe (kernel module name is just overlay, not overlayfs):
Code:
modprobe overlay


P.S. StretchDog (and I think also DevuanDog) will boot by default with overlayfs when using live-boot

Fred

It's not for xenialdog I'm using overlayfs, so not really needing it working there - just experimenting with overlayfs more generally for use with void linux.

It was just that I was booted up in xenialdog and one point and just doing simply overlayfs experiments at the time, so was trying it from there.

Yeah, I'd already tried 'modprobe overlay' in xenialdog but didn't seem to be working, though I may have done something wrong at the time.

No problem though, it's working in void linux for me, which is where I want it anyway.

wiak

If overlayfs was in the kernel (as should normally be by default, the following little test of it should work, but doesn't in either XenialDog64 or BionicDog64 and 'modprobe overlay' doesn't help:

Code:
cd /tmp
mkdir lower upper workdir overlay
sudo mount -t overlay -o \
lowerdir=/tmp/lower,\
upperdir=/tmp/upper,\
workdir=/tmp/workdir \
none /tmp/overlay


Pity really. Could use aufs instead of course, but I've working on using overlayfs with an underlying Void Linux install so aufs no interest to me. Anyway, I can actually use my Void Linux install itself instead since overlayfs works fine in there - just liked the option of continuing the experiments even when I was booted into XenialDog but no big deal.

Hi wiak, I tested your code on Stretch (after doing "modprobe overlay") and got error message (probably the same as you, I guess)
Code:
mount: wrong fs type, bad option, bad superblock on overlay,
       missing codepage or helper program, or other error

Then I tried if it works on a mounted partition (in my case 'tmp' folder on sda7) and seems to me it's OK.
My guess is that if you a use a directory inside (the already mounted with aufs) filesystem, then it doesn't work, but outside it does work from my test, anyway, no error message appears.

Code:
mkdir -p /mnt/sda7/tmp
cd /mnt/sda7/tmp
mkdir lower upper workdir overlay
mount -t overlay -o \
lowerdir=/mnt/sda7/tmp/lower,\
upperdir=/mnt/sda7/tmp/upper,\
workdir=/mnt/sda7/tmp/workdir \
none /mnt/sda7/tmp/overlay


EDIT: Tested also now on XenialDog using sda7/tmp, looks OK to me:
Code:
root@xenial64:~# mount | grep overlay
none on /mnt/sda7/tmp/overlay type overlay (rw,relatime,lowerdir=/mnt/sda7/tmp/lower,upperdir=/mnt/sda7/tmp/upper,workdir=/mnt/sda7/tmp/workdir)


EDIT2: Mmm.. just found that it works also in tmpfs, e.g. folder /mnt/live
Code:
cd /mnt/live/tmp
mkdir lower upper workdir overlay
mount -t overlay -o \
lowerdir=/mnt/live/tmp/lower,\
upperdir=/mnt/live/tmp/upper,\
workdir=/mnt/live/tmp/workdir \
none /mnt/live/tmp/overlay

The /tmp directory was a tmpfs filesystem in earlier distributions, but nowadays it's not anymore in Debian and Ubuntu, maybe in Void it still is ?

Fred

Ah, OK. I should gave checked that too. That's good though, I'll try that too and chech that difference with void when I'm next on computer. Posting from android phone just nw... What you write makes sense tho so I just need to not use aufs mount for my experiments more generally.

Thanks, wiak
