AskLinux: Dual boot of Fedora qnd Ubuntu - How many boot partitions should I have?!

1 hour 2 min ago

Okay, I've never really had a dual boot config of two linux OSs and this kinda gets confusing for a n00b like me!

My basic system partitions look like this..

Now this was my original plan, but I was scared to use a sinle /boot partition for two linux os since i couldnt guarantee conflicts wont occur. Maybe they'd get their kernels mixed up or some other form of dark magic?!

So, I created two different /boot partitions of 512MB each, that share a common /boot/efi. I read that's where the grub2 bootloader resides. However, I was wondering.. what would happen if a common /boot folder was used?

Further, while the latest kernel of ubuntu 17.10 (kernel-4.13-generic) is being used, the fedora kernel wasn't even detected. So, I manually mounted the /boot partition of Fedora to /mnt and ran # update-grub after which grub2 finds the original 4.13 kernel of fedora. However, the latest 4.15 kernel is nowhere to be found in the boot menu, even though rpm -qa | grep kernel lists it. So, how can i fix it? Would using a common /boot folder eliminate this?

Linux security modules

6 hours 12 min ago

Hello everyone! I am doing a thesis about linux security modules (SELinux, Tomoyo, AppArmor). And now I have to do some practical work... I was thinking to create a few virtual machines and simulate an "hacking attack", for each security module and by doing that I would get an information what are the weak sides and what are strong sides of each module... Now I am not really an expert and I don't really know that much about all that, so I need help / guidance where to start, or is there a safe way to simulate an attack... Any piece of information would be extremely helpful... Thanks.

Possible pentadactyl replacement (tridactyl)

12 hours 45 min ago

So I've been using the pentadactyl addon (vim-like keybinds/commands) on firefox for years, and as of a few months ago, it became too inconvenient to use older/custom versions of firefox just to keep that working.

But I just recently found an addon with a similar name called tridactyl, which seems to work very similarly. Just wanted to 1) get some discussion going about this addon, and 2) maybe get more information about it from those who have used it longer, or maybe know the developer.

It seems to be in beta now, and certain features are stated to be implemented later (like a proper / search). But if those things do get impolemented, I would consider this the closest replacement for pentadactyl thus far. Anyone else thinking the same?

Looking to revive a 2007 iMac with a dead internal HDD. What’s a good basic distro for me?

Sat, 2018-02-17 20:29

I’ve used Linux GUI before on a netbook, and a Windows XP machine for VLC. I’m looking to use this iMac for basic video streaming and maybe attach an external to host files on my local network.

Here’s my question: unetbootin won’t work for a bootable iso via usb. Can I use a different Mac to install Ubuntu (or Mint, etc) as a live install to another usb stick and have that be my bootable OS?

Massive "find" gotcha

Sat, 2018-02-17 19:07
$ mkdir find-tmp $ cd find-tmp $ echo -n "a" > foo $ ls -l foo -rw-r--r-- 1 alan users 1 Feb 17 17:55 foo $ find . -size -1M $ find . -size -2M . ./foo $ find . -size -1000000c . ./foo $ find . \( -size -1M -o -size 1M \) . ./foo $

From the man and info pages: File uses n units of space, rounding up. (though the Centos man page doesn't mention this)

There is no mention of the actual effect of this rounding: one character is rounded up to the "M" (Mebibyte, 1048576 bytes) unit (though the man page uses "Megabytes"). The "less than" test then fails. Or'ing in a an "equals" test makes it work.
