mount /home, /var and /tmp to the same partition

Kwahab · 10-12-2009, 11:49 AM

Have 2 physical discs one partition each (sda1 & sdb1).

Want to mount / to sda1, but want /home, /var and /tmp on sdb1 without making separate partitions for each.

I think it can be done with the --bind option.

Can anyone help with the syntax? fstab entry?

Thanks

man mount
man fstab

Use a partitioning tool like fdisk to make them

Use mount to mount them

configure your fstab file to have them mount where you want them every time you turn the machine on.

don't use fdisk ... use qtparted or gparted or parted. fdisk is more difficult to use ...correctly

It is unclear to me why you want to do this...

I would not do it---simply because it would create potential confusion later. Why not make separate partitions?

What? Because each additional partition is an additional failure mode, that's why.

That's an interesting bit of logic....For myself, I do not use multiple partitions. But I also use drives that are much bigger than I need---so I almost never worry about things filling up.

Well, for me space is an issue and by making separate partitions all flexibility is lost. If I dedicate space for /tmp and /var, my /home will be (permanently) smaller. That would keep me awake at nights.
