Shouldn't it vary according to the amount of RAM available on the system? Or is the backing store (swap) more relevant? Anyway ...

Oh right :-) Seems like I was fat and happy in February with "-s=4194304" in fstab and "df -h /tmp" returning 1.8G available. I don't know why or when it stopped working in the meantime. Maybe daily should report failed mounts? I mean, normally, something like that is hard to miss, but with /tmp it's not so obvious. Just a thought. I guess I tend to avoid modifying login.conf to avoid having to fix issues reported by sysmerge after an upgrade. But in reality those don't occur that often and I'm just being overly sensitive. Right now login.conf contains: > daemon:\ > :ignorenologin:\ > :datasize=4096M:\ > :maxproc=infinity:\ > :openfiles-max=1024:\ > :openfiles-cur=128:\ > :stacksize-cur=8M:\ > :tc=default: > ...

Is it possible to do something like "doas daemon ..."? I'll switch fstab back to use this size for /tmp and check after the next reboot if it gets mounted as expected ... Cheers, Robb.
