Fail to build (/dev/null: Permission denied)

[travankor]

I type sudo make bootstrap-all, and this fails because of /dev/null: Permission denied. Any idea of what I am doing wrong?

I'm not sure if it is permissions related.

[Travankor build_dir]$ ls -ld dev
drwxr-xr-x 2 travankor users 4096 Aug  3 20:35 dev
[Travankor build_dir]$ cd dev
[Travankor dev]$ ls -l

Unless you have some fancy GRSEC, SELinux or such, I would suspect your /home mountpoint being mounted with 'nodev' option. If it's the case, try:

mount -o remount,dev /home

As root, and then it should work.

On todo list I actually have a item to make it buildable with bubblewrap, wich would no longer require root to do so (but user_ns), so in future it will be slightly better.

Yep, that fixed it. Thanks for responding so soon.
