Changes to FSTAB mounting, now uses systemd?

[James Crook]

so i had a nice fstab which depended on a few things being mounted before the next. I'm using mergerfs and then using bind to make the location a bit easyier to remember. After a new install of proxmox 7 it seems that everything is being mounted at once, which can then cause an issue with my mergerfs and bind not working as the underlieing disks were not mounted

I get the following errors from syslog

I've read a little bit about "x-systemd.requires=" but it still fails with the same message, when setting on the last entry
https://github.com/systemd/systemd/commit/3519d230c8bafe834b2dac26ace49fcfba139823

Do i need to add each disk as an entry for the fuse.mergerfs mount before, and keep the last mount with it as well ?

yeah, you likely need to encode those dependencies (you can take a look at the generated units with systemctl show ... to see what gets autodetected and what you need to add). man systemd-fstab-generator / man systemd.mount has all the options (but of course - using mount units directly instead of generating them via /etc/fstab is also an option )

Am i showing my age then, using fstab
:teehee:

no, fstab is totally fine to use for things like this - just make sure to give systemd all the info it needs to properly order/.. the mounts
