Re: startup: separate /var partition hoses /run, shm (shared memory)?
You're quasi running Sid, this explains that you could run into trouble.
Some software does expect:
spinymouse@qrc:~$ df -hl | grep run
tmpfs 741M 944K 740M 1% /run
none 5.0M 0 5.0M 0% /run/lock
none 1.9G 0 1.9G 0% /run/shm
none 100M 16K 100M 1% /run/user
But your customized Sid doesn't provide it. IMO you should switch to
Debian testing or to Mint Ubuntu version, if you prefer Mint.
I guess base-files is installed?
Can't you copy /var to / and reinstall base-files?
