Is udev-mount really needed?

[Matte88]

Continuing from here just to keep discussion clear and on its own.

What's happening with udev-mount? Is safe to remove it from runlevel (since it was not there before)?

Code: Select all

rc-service udev-mount describe
* mount devtmpfs on /dev

Code: Select all

cat /etc/mtab | grep udev
udev /dev devtmpfs rw,nosuid,relatime,size=10240k,nr_inodes=381156,mode=755 0 0

Code: Select all

cat /etc/fstab

I don't know, but I have it in the sysinit runlevel on my main laptop running up-to-date ~amd64 Gentoo:

Code: Select all

meshedgedx fitzcarraldo # rc-update show -v | grep udev
                 udev |                                        sysinit
           udev-mount |                                        sysinit

Code: Select all

meshedgedx fitzcarraldo # cat /etc/fstab
/dev/sda6    /                  ext4       user_xattr,noatime           1 1
/dev/sda7    /home              ext4       user_xattr,noatime           1 2
/dev/sda3    /boot              ext4       user_xattr,noatime,noauto    1 2

Read the following post in the Gentoo Forums, which I think I understand! Notice his Point 3, in particular.
