Trouble booting read only btrfs snap shots

za flag

I've set up my system with btrfs subvolumes. I've got btrfs assistant, snapper and grub-btrfs installed and working. However my problem is when I try to boot from a past snapshot I fail to load gdm3. I'm sure this has to be caused by the fact that Snapper only creates read-only snapshots. I've made sure that /var/tmp /var/cache and /var/log are all writeable by creating separate subvolumes for them and mounting them in my fstab. On my arch system, this was all I had to do to get a bootable system on read-only snapshots, even though a few services failed. My snapd is also not happy about being read-only. Snapd isn't much of a problem as I'm just needing to boot to roll-back my system. I'd ideally like to be able to boot from a read-only snapshot and be able to roll back my system using btrfs-assistant, which is a gui program. As of now I can boot from a past snapshot wait for it to get hung up on gdm.service then get in a tty and roll it back by hand. What else needs to be writeable for gdm to start?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
