Given the current situation in the server room:

https://jungle.bsc.es/grafana/d/EKkKVvLVz/hut?orgId=1&from=now-30d&to=now&timezone=browser&refresh=5s

We won't be able to maintain the machines much longer without causing hardare issues. Given that some critical services are served there, they should be moved ASAP. It may be posible to prepare a backup machine to keep them running elsewhere.

From nixos-install, unshare --mount-proc fails:

xeon04:~ # strace -f unshare --mount-proc
...
unshare(CLONE_NEWNS)                    = 0
mount("none", "/", NULL, MS_REC|MS_PRIVATE, NULL) = 0
mount("none", "/proc", NULL, MS_REC|MS_PRIVATE, NULL) = 0
mount("proc", "/proc", "proc", MS_NOSUID|MS_NODEV|MS_NOEXEC, NULL) = -1 EBUSY (Device or resource busy)

kexec?
