here is my fstab
Code:
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# /dev/sda2
UUID=9f82a725-2797-41ee-a4e5-507a24941b86 / ext2 noatime,errors=remount-ro 0 1
# /dev/sda1
UUID=a154b93d-6156-4f6e-8cf6-840fad676ea2 /boot ext2 noatime 0 2
# /dev/sdb1
UUID=e646edf4-f7a2-4647-a6db-8af8c99e761a /home ext2 noatime 0 2
#mount tmp dirs in ram memory, to reduce writes
tmpfs /tmp tmpfs defaults,noatime,mode=0777 0 0
tmpfs /var/tmp tmpfs defaults,noatime,mode=0777 0 0
tmpfs /var/log tmpfs defaults,noatime,mode=0777 0 0
#mount the squashfs /usr directory and put a writable layer on top
/.filesystem/usr/usr.sqfs /usr squashfs ro,loop,nodev 0 0
unionfs /usr unionfs nodev,noatime,dirs=/.filesystem/usr/overlay=rw:/usr=ro 0 0
I would like to keep my home dir writeable, because that's where i download files and edit my documents. And this is something i would like to keep doing
maybe you can let this depend on a var in the script? writablehome=1 for example
maybe i could change my fstab to let my /usr dir make use of the aufs filesystem as well instead of unionfs
