| Code: | /dev/sda1 /boot ext4 defaults,noatime 1 2
/dev/sda2 none swap sw 0 0
/dev/sda3 / ext4 noatime 0 1
/dev/sda5 /opt ext4 defaults,noatime,nodev 0 1
/dev/sda6 /usr ext4 defaults,noatime,nodev 0 1
/dev/sda7 /usr/portage ext4 defaults,noatime,nodev,noexec,nosuid 0 1
/dev/sda8 /var ext4 defaults,noatime,nodev 0 1 |
Is how the system is set atm, server will be the same, although i will remove /usr/portage
so i am gussing if i remove sda8 it should look something like
| Code: | /dev/sda1 /boot ext4 defaults,noatime,nodev 1 2
/dev/sda2 none swap sw 0 0
/dev/sda3 / ext4 noatime,nodev 0 1
/dev/sda5 /opt ext4 defaults,noatime,nodev 0 1
/dev/sda6 /usr ext4 defaults,noatime,nodev 0 1
/dev/sda7 /var ext4 defaults,noatime,nodev 0 1
/dev/mapper/home /home xfs defaults,allocsize=512m 0 0
tmpfs /tmp tmpfs size=2G defaults,noatime,nodev,nosuid 0 0
proc /proc proc defaults 0 0
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0 |

| Although not likely to be important, you missed nodev on / and /boot. You could mark /var noexec, but only if you do not build on it. |

well the worst that can happen is that it will tell me it cant build there, which is what i think it did to me before which is why i removed it, if memeroy serves me right it complained about /var/tmp/portage
I edited the above post so i can copy and past it when i reinstall

Does nodev on / still permit the use of the /dev files? Or is the kernel happy once
udev has created them? I've always been a bit confused about nodev on anything
but /home partitions.

I wouldn't recommend this to anyone yet, but on my laptop I just have an ext2 /boot and give the rest of the disk to btrfs subvolumes. Everything can have as much space as it wants while having separate mount flags.

btrfs might get a look in when it is stable

nodev applies to device nodes on the filesystem in question. In a typical system, /dev is a tmpfs or devtmpfs, and is therefore not part of /. Thus, device nodes in /dev are not affected by the nodev option on /. You might get into trouble if you use a static /dev with pre-created devices, but there is no reason to do that these days. |

I did this for a long while.
I moved away from it as soon as humanly possible. I have my own anecdotal evidence it was not up to snuff (the way i was using it, at least) |

I ended up going away from the usual partition for each section, for my personal workstations with one disk that update frequently, because pooling all disk space gives highest flexibility.
For systems that aren't supposed to change often and multiple disks/disk types, then partition per may make sense... But for the most part my typical linux machine has a small /boot partition (some even don't!), a swap partition (some don't and use swap files instead!), and the root partition with everything on it. A lot less hassle.
I got sort of tired of the partitions because I tended to make modifications on my whole system and ended up needing to back up the whole system anyway because I don't remember which partitions I changed... that means it defeats the purpose of keeping more frequent backups of, say, /home which has the most changes, and none of /tmp, which we don't care about.
(And I've been bad. I store files in /tmp expecting them to stay there and then openrc default then blows /tmp away...)
